For Iran this embarrassment is compounded by an increasing crescendo of articles that not only highlight the destruction at the site but also point fingers at who did it.

The evidence is piling up for Iran’s leadership: A mysterious explosion at a warehouse at its sensitive and advanced nuclear facility of Natanz has caused deep and lasting damage that has set back its nuclear work. For Iran this embarrassment is compounded by an increasing crescendo of articles that not only highlight the destruction at the site but also point fingers at who did it. Al-Jarida media in Kuwait had first alleged it was a cyberattack and now The New York Times has said that Israel was responsible.

Iran had already begun to shift focus from an “accident” as it first claimed the mysterious explosion was on July 2, to a more serious incident. Iran had to weigh the consequences of misleading international atomic energy inspectors and officials. After all, if Iran said it as an accident and then said it was attacked, that might make Tehran look incompetent. Having shot down a civilian airliner in January the regime already looks incompetent.

The New York Times piece alleges that a powerful bomb was behind the attack. The explosion harmed an area that relates to advanced centrifuges. Iran has said over the past year that it is increasing the number of IR-6 centrifuges at Natanz. Last year there were reportedly some 60 IR-6 advanced centrifuges being used by Iran and uranium hexaflouride gas was being fed into some of them. Iran’s Tasnim news showed off a truck containing a cylinder of uranium hexafluoride gas leaving the enrichment facility at Natanz last year. Now a key facility in the supply chain and development of this advanced work has been badly damaged or destroyed, reports indicate.

For now Iran is concerned about the embarrassment of the Natanz incident. ISNA, Fars News, Tasnim and other Iranian media that are linked to the state or state-run are not pointing fingers or discussing the incident. Iran’s message was that the explosion was an accident and that Iran would investigate and determine if it was intentional and then Iran would weigh its response.

Neighboring countries are holding their breath. Kuwait’s media has stopped covering the incident and Gulf media is also waiting to see what may happen. Iran is in the middle of a series of political crises. The Foreign Minister Javad Zarif was in parliament over the weekend where he was insulted and heckled. He has been called “liar” by key media and officials. Zarif always projects an air of happy arrogance abroad where he feels most comfortable and is often worshiped by western diplomats. But at home Zarif can’t pull the wool over everyone’s eyes all the time, and he has been castigated. In addition, the speaker of parliament, Mohammed Bagher Qalibaf looks to play an increasing role in foreign policy. He has been speaking with Palestinian factions recently, urging hatred of Israel. Iran has also triggered the nuclear deal dispute mechanism, oddly just a day after the Natanz incident.

To understand Iran’s Natanz reaction we must thus understand that there is internal political chaos bubbling under the surface in Iran. There is economic uncertainty. There are a variety of problems in Iran and the nuclear drive to add centrifuges and gas and all of this is just a piece of the puzzle. Iran’s IRGC is itching for a fight. It has lost its key official, Quds Force head Qasem Soleimani in a January US airstrike. It’s new Quds Force commander Esmail Ghaani is an expert on Afghanistan, not on Israel and the Arab world. Yet he was in Syria in June to oversee Iran’s regional game plan. But Iran knows that its ally in Syria is undergoing an economic disaster from US sanctions, and its Hezbollah ally in Lebanon is also facing economic chaos in Beirut. Iran’s only real victory is on the world stage where Russia and China want to help it end an arms embargo. Iran would like that to happen so it can continue to funnel weapons to groups like the Houthis in Yemen. Even on that file Iran has seen two weapons shipments intercepted by the US Navy in the last year.

Natanz is important and the increasing spotlight put on the damage and accusations of who did it will rile up Iran’s IRGC and demands for a response. But Iran will have to choose carefully its next moves in a region that is a powder keg and one where it is trying to open up diplomatic avenues.

 

Israel was behind blast at Iran nuclear site, Mideast intel official tells NYT

Officials says powerful bomb was used to damage building involved in centrifuge production at Natanz, denies Israeli connection to other recent fires in the Islamic Republic

A fire that damaged a building used for producing centrifuges at Iran’s Natanz nuclear site was sparked by Israel, a Middle Eastern intelligence official told the New York Times on Sunday.

The unidentified official said the blast Thursday at the Natanz nuclear complex was caused by a powerful bomb.

The Middle Eastern intelligence official said Israel wasn’t linked to several other recent mysterious fires in Iran over the past week.

The report came as Iran admitted that Natanz incurred “considerable” damage from the fire last week, as satellite pictures appeared to show widespread devastation at the sensitive facility.

Iran had sought to downplay the damage from the blaze, though analysts said it had likely destroyed an above-ground lab being used to prepare advanced centrifuges before they were installed underground.

“We first learned that, fortunately, there were no casualties as a result of the incident, but financial damages incurred to the site due to incident were considerable,” said Iran’s atomic agency spokesman Behrouz Kamalvandi.

He confirmed that the damaged building was a centrifuge assembly center and not an “industrial shed,” as earlier claimed.

“More advanced centrifuge machines were intended to be built there,” he said, adding that the damage would “possibly cause a delay in development and production of advanced centrifuge machines in the medium term.”

Authorities have pinpointed the source of the fire, but are withholding the information for national security reasons, he said.

The building was first constructed in 2013 for the development of advanced centrifuges, though work was halted there in 2015 under the nuclear deal with world powers, he added.

When the US withdrew from the nuclear deal, the work there was renewed, Kamalvandi said.

He said that the fire had damaged “precision and measuring instruments,” and that the center had not been operating at full capacity due to restrictions imposed by Tehran’s 2015 nuclear deal with world powers. Iran began experimenting with advanced centrifuge models in the wake of the US unilaterally withdrawing from the deal two years ago.

Satellite images of the Natanz site published Sunday by the London-based Iranian news site Iran International appeared to show that the site had incurred more significant damage from a mysterious blast last week than what Tehran had initially disclosed.

The photos showed most of the building flattened with debris scattered around the perimeter, indicating that it had been targeted in an explosion.

Experts assess that the damage from the apparent explosion has set back Iran’s nuclear program by a year, according to Israel’s Channel 13 news. The network said Sunday that the lab in Natanz where advanced centrifuges are assembled had been destroyed.

In 2018, Iran showed off IR-2, IR-4 and IR-6 centrifuges at the site, in what was seen as a warning to Europe to stick to the nuclear deal after the withdrawal from the accord by the US. Pictures have also purported to show IR-8 centrifuges at Natanz, though Iranian officials have also said the site could not yet handle the ultra-advanced centrifuges.

The fire was one of a series of mysterious disasters to strike sensitive Iranian sites in recent days, leading to speculation that it may be the result of a sabotage campaign.

Also Sunday, Prime Minister Benjamin Netanyahu announced that he would extend the term of Mossad chief Yossi Cohen until June 2021, citing unspecified “security challenges.”

The spymaster is famed in the Mossad ranks as an operations man. Under his watch, the Mossad has reportedly grown in personnel and budgets and has focused on espionage operations targeting the Iranian nuclear program.

An Israeli TV report Friday night said that Israel was bracing for a possible Iranian retaliation if it determines Jerusalem is behind the Natanz explosion.

Defense Minister Benny Gantz played down the speculation earlier Sunday, saying that not everything that happened there could be blamed on Israel.

On Saturday, an explosion reportedly damaged a power plant in Ahvaz, Iran, which was later followed by reports of a chlorine gas leak at a petrochemical center in southeast Iran.

The previous week a large blast was felt in Tehran, apparently caused by an explosion at the Parchin military complex, which defense analysts believe holds an underground tunnel system and missile production facilities.

The Fars news agency, which is close to the country’s ultra-conservatives, initially reported that the Parchin blast was caused by “an industrial gas tank explosion” near a facility belonging to the defense ministry. It cited an “informed source” in saying the site of the incident was not related to the military.

However, this was largely disputed by defense analysts as satellite photographs of the Parchin complex emerged showing large amounts of damage at the site.

Iran long has denied seeking nuclear weapons, though the IAEA previously said Iran had done work in “support of a possible military dimension to its nuclear program” that largely halted in late 2003.

Western concerns over the Iranian atomic program led to sanctions and eventually to Tehran’s 2015 nuclear deal with world powers. The US under President Donald Trump unilaterally withdrew from the accord in May 2018, leading to a series of escalating attacks between Iran and the US, and to Tehran abandoning the deal’s production limits.

 

With Iran in its sights, Israel launches new spy satellite into orbit

Defense Ministry says Ofek-16, an ‘optoelectronic reconnaissance satellite with advanced capabilities,’ blasted off at 4 a.m., undergoing tests after entering orbit

Israel launched a new spy satellite into orbit from a launchpad in the center of the country early Monday morning, the Defense Ministry said.

“The Defense Ministry and Israel Aerospace Industries successfully launched into space the reconnaissance satellite ‘Ofek 16,’ which entered into its orbit,” the ministry said in a statement.

Israel is one of a small number of countries in the world that operate reconnaissance satellites, giving it advanced intelligence-gathering capabilities. As of April, this cadre included Iran, which successfully launched a spy satellite into orbit after years of failed attempts.

“Our network of satellites lets us watch the entire Middle East — and even a bit more than that,” said Shlomi Sudari, the head of IAI’s space program.

The reconnaissance satellite was fired into space at 4 a.m. using a Shavit launch vehicle that took off from a launchpad in the Palmachim air base in central Israel, the ministry said.

The Ofek-16 is an “optoelectronic reconnaissance satellite with advanced capabilities,” the ministry said. It is the latest satellite in the Ofek series to be launched into space, following the Ofek-11, which entered orbit in 2016.

According to Sudari, the Ofek-16 is the “brother” of the Ofek-11, containing many of the same capabilities, along with a few “light improvements, in terms of precision.” Defense Ministry officials refused to comment on the jump in the name, from Ofek-11 to Ofek-16.

“The Ofek-16 is highly advanced, including breakthrough ‘blue and white’ technology that serves our defense interests,” Sudari said, using a term that refers to the colors of the Israeli flag to signify domestically produced capabilities.

Though the main function of the new spy satellite will likely be monitoring Iran and developments in its nuclear and missile programs, defense officials denied any symbolism in conducting the launch amid growing reports that Israel was responsible for a number of recent explosions in the Islamic Republic, including one at a uranium enrichment facility and another at a missile production plant.

“The timing was planned far in advance,” Sudari said.

Sudari said the Ofek-16 would operate on a low-Earth orbit, similar to the other Ofek satellites.

“Under the original launch plan, the [Ofek-16] satellite entered orbit around the Earth and began to beam back data,” the Defense Ministry said early on Monday.

Engineers from the ministry and Israel Aerospace Industries began performing a series of tests to ensure that the satellite was operating correctly. The ministry said these checks would continue “until the satellite enters full operation shortly.”

Amnon Hariri, the head of the Defense Ministry’s Space Department, beamed that the launch was “eloquent,” with no hiccups.

Once operational, the satellite will be operated by the Israel Defense Forces’ Unit 9900, a visual intelligence detachment that controls all of the nation’s spy satellites.

“The State of Israel’s technological and intelligence superiority is the cornerstone of its security,” Defense Minister Gantz wrote on Twitter. “We’ll continue to strengthen and fortify Israel’s strength on every front and every place.”

This was the first launch of an Israeli spy satellite into space since the Ofek-11 in September 2016.

The Ofek-11 experienced initial technical issues shortly after launch, but engineers on the ground were able to stabilize it and get it working.

According to the Defense Ministry, there were no such issues with the Ofek-16.

Last year, Israel also put the Amos-17 communications satellite into orbit, using a SpaceX rocket that was launched from Cape Canaveral, Florida.

Israel launched its first satellite, the Ofek 1, into space in 1988, footage of which was released by the Defense Ministry in 2018.

It was not until seven years later, in 1995, that Israel launched a reconnaissance satellite into space capable of photographing the Earth.

The things that go bump in Iran’s nights

July 6, 2020

A detailed analysis of the three recent “kaboom” events in Iran.

https://www.centerforsecuritypolicy.org/2020/07/03/the-things-that-bump-in-irans-nights/

For the third time in five days, Iran has been rocked by massive explosions yesterday (July 2).  All three are mysterious, with the only clarity being that Iranian official explanations lack credibility or consistency.  In other words, we do not know for sure what happened, or what was destroyed, but we do know the Iranian government is unable to tell the truth about any of them.

THE FACTS AS KNOWN

The first blasts occurred at the Khojir missile facility, which the Iranians erroneously say was the Parchin military base. They further claimed that it was in a civilian area outside the military site.  Satellites show it was at Khojir, close but not the same as Parchin, and that it was in the center of a missile solid fuel production complex. At the same time, there was an explosion and fire at a power plant complex in Shiraz, which plunged the city into darkness. For an analysis of these two blasts, click HERE.

Two days later, on June 30, a large fire and subsequent series of explosions destroyed an underground complex beneath what the Iranians described as a medical clinic in the Tajrish Square area of Tehran itself.  The blast caused a fire, which was followed by several additional secondary explosions of considerable magnitude.

Video of the secondary blasts can be seen HERE at 36 seconds and HERE at 19 seconds.

Iranian authorities at first claimed this was an explosion of medical oxygen tanks stored in a second-story below ground level in a modest five-story medical clinic for MRIs named Sina Athar.  Gas tanks of the size required to produce the blasts in the video would have had to have been larger than the oxygen tanks commonly seen in U.S. hospitals and medical/nursing facilities, which again begs the question of why the Iranian government would place multiple industrial sized oxygen tanks in an enclosed space under a small medical facility which conducts MRIs and does not need to use large amounts of oxygen.

To deepen the plot, the next day the Iranian government issued an arrest warrant for several people, while the Iranian National Gas Co. denied this was a gas explosion.  Local governmental authorities changed the official story as well, and began claiming the blasts were a result of an electrical fire without giving any coherent explanation as to what the fuel source was of the large initial and secondary explosions.  Iranian TV outlets did not help stem the speculation because, as they had done with Parchin, they released footage that was clearly tightly cropped and showed damage at the edge of the destruction, with the source of it inescapably behind the camera shots.  We have no footage yet of the building damaged itself, which given the force of destruction of the secondary blasts captured on social media must have destroyed the building.

At this point, there is no public knowledge of a secret facility underneath this clinic or an adjacent building, so it would be impossible to analyze what might have been damaged if this was something more than just a clinic.

Two days later, on the morning of July 2, a massive explosion rocked the Natanz nuclear facility near Isfahan. Immediately the Iranians admitted a minor explosion occurred, but claimed it occurred in a building that was an empty, minor storage building under construction at the edge of the facility. This is itself suspicious since Iran is required under previous nuclear agreements, including the 2015 JCPOA,  to report any new construction at the Natanz facility, but had not done so. Moreover, not only have the Iranians thus far failed to provide a reported cause of the explosion, but the imagery provided by Iranian opposition groups shows a very large, devastated building that would have been caused by a large blast.

By evening, an unknown opposition group, named the “Panthers of the Nation,” claimed that it had attacked the Natanz plant. Some opposition groups claim a newly-constructed centrifuge assembly workshop was destroyed.  Arms control groups in the West noted that the building was previously identified by the Atomic Energy Agency of Iran as a centrifuge assembly plant.  Iranian opposition groups released an image of an entry doorway, above which it clearly is marked as a centrifuge assembly plant. For Images, click HERE.

Finally, on July 3, the Iranian regime still did not admit that the incident in Natanz was sabotage, but did say it would withhold further comment or explanation given a security investigation. Moreover, it oddly warned the world that any cyber attack on its nuclear installations would be met with a “withering” response.

ANALYSIS

Those are the known facts of what happened.  But what explains this unlikely coincidence of events?

One cannot rule out that despite all the inconsistencies and clearly fabricated and incredible explanations, Iran simply had a bad week of accidents.  Iran’s system is so corrupt that Iranians have come to regard the constant stream of catastrophes to which they are subject as the wages of the vast incompetence.

However, while the explosions may be coincidental and resulting from the incompetence of Iranian authorities driven by pervasive corruption, it is looking increasingly possible that someone is incrementally sabotaging the Iranian nuclear and missile program.  This suspicion is strengthened by the claims by an opposition group that the events at Natanz were the result of its attack. The highly sensitive nature of at least two of sites involved in these incidents further deepen the suspicion.

If this is indeed the hand of some entity seeking to damage Iran’s nuclear program, and because these events are so tightly spaced together to suggest a common actor, we can draw some preliminary conclusions.

Starting with the Iranian opposition group, this is the first time anyone has heard of them.  It could be either a group acting alone, a group acting in coordination with a foreign power, or a foreign power acting using the fictitious cover of domestic opposition group. This is probably not a group acting alone, since the sophistication of collecting at the site and operational intelligence, as well as striking so broadly and consistently without leaving a trail could hardly have been done without some highly capable assistance from a nation-state.  Moreover, there would have been no incentive to avoid claiming credit for all the attacks, since publicizing potency is the currency of attraction for opposition groups.  More likely, ths was either an opposition group working with a foreign power, or a foreign power acting with a fictitious cover. But who? The two likely suspects are clearly the United States and Israel.

Israel and the U.S. share a common aim of stopping Iran as soon as possible from advancing in its nuclear program. And yet they have different aims surrounding the context of any operation.  The United States has a history of acting overtly using its own power only. Nor does it have a tradition of keeping the attacks ambiguous.  When General Soleimani was killed last winter, the United States fairly quickly accepted the credit.  Indeed, such an overt act advances traditional American foreign policy goals since it draws a red line, which when crossed triggers an American reaction and is followed by the implied warning to the offending country that it will face worse if it tried again.

Was this an U.S. or US-Backed Attack?

Deterrence is central to U.S. calculations when acting.  For the United States, ambiguity generally dilutes the message of threat underpinning such deterrence. Generally as well, the United States does not fear escalation since the preponderance of U.S. power guarantees that the offending country will be further defeated and humiliated, deepening the effect of deterrence. As such, given our historical reliance on our own power and tapping its use to establish deterrence, the United States rarely employs sophisticated James Bond-like operations when not needed and could be easily done overtly instead. Traditionally, we would just rather more brazenly bring our might and reach to bear without concern for either the attack being clearly an attack or our being identified as the attacker.  Moreover, the U.S has little or no incentive in an attack being conducted subtly enough to allow the Iranian government to save face.

Finally, the United States does not work with Iran’s opposition groups, much to their great frustration. As such, the only real option for the United States, if it was behind these attacks, was to use its own forces on the ground or remotely. To use special forces spread out over a week rather than in one coordinated attack, however, would needlessly risk compromising surprise, thus endangering special forces without any real tactical or strategic rationale.

Was this an Israeli or Israeli-Backed Attack?

Israel shares the American interest in stopping Iran’s program, but it has several additional concerns that change the context and method in which it would conduct such an attack.  Hizballah right now has close to several hundred of thousands of missiles pointed at Israel from Lebanon (some with very substantial warheads), with many more in Hamas’s hands from Gaza. Hizballah and Hamas can be expected to respond to any overt Israeli attack on Iran. While Israel can handle such a reaction, the destruction and death in Israel from a retaliatory war would not be inconsequential, and the occupation of both parts of Lebanon and Gaza inevitable, with all the agony that would entail.

Second, Israel is under great pressure from Europe on its own reported nuclear program.  It also harbors great worries about the American left.  Over the last decade, policies challenging Israel’s purported nuclear program which were long peddled by the European Union have finally gained traction with a U.S. Democrat administration, and the overall direction of the Democratic party has convinced Israelis that they no longer have its support on their purported nuclear program.

Earlier this decade, the Israelis were horrified when the Obama administration abandoned Israel as protector at Nuclear Non-Proliferation (NPT) review conferences, despite solemn assurances over 50 years and seven administrations to never do so. And Israel was not even notified ahead of the abandonment, but was broadsided by a coordinated US-EU diplomatic effort.   As such, Israel fears a push for a nuclear free weapons zone in the Middle East focused on the idea that Iran alone cannot be asked to disarm or surrender its nuclear program, and thus any genuine move to disarm Iran would require simultaneous, or even preceding, Israeli disarmament.  Israel expects that an overt attack would trigger a massive international effort to focus on Israel’s reported nuclear program, which the Democrats here would also embrace. So the Israelis are loathe to overtly attack Iran given the expectation that the resulting diplomatic upheaval would settle eventually into primarily a focused effort to impose immense international pressure on Israel’s reported nuclear program.

Over recent years, Israeli institutes and reportedly even its security structures have gamed out repetitively how Iran would react to an Israeli strike on its nuclear program. The results almost always suggested that if the attacks were uncredited and subtle, the Iranians would prefer to save face and simply call them industrial accidents in insignificant buildings or facilities. If Iranian officials were to admit an attack on the nuclear program, or to be unable to deny it, they be would be forced to retaliate overtly — namely war via Hamas and Hizballah.  But if even partially deniable, they would prefer not to escalate. While a resulting war would be painfully damaging to Israel, it would decisively wipe Hizballah out, which in turn would destroy their ability to retain their grip over Syria and Lebanon.  In short, Iran has little incentive to seek an escalation with Israel, and Israel does have an incentive to allow the Iranian regime to save face.

So, Israel has every interest to have Iran save face and just digest the attacks.  Indeed, it should be noted that Israel never claims credit for its fairly frequent attacks on targets in Syria, since it similarly seeks to give the Russians and Syrians the opportunity to save face and refrain from retaliation.

Finally, Israel does work with Iranian opposition movements, and could easily use their infrastructure to operate on the ground in Iran to conduct such attacks.

THE BOTTOM LINE

Given these considerations, operating under the unproven assumption that these series of accidents in Iran were in fact a coordinated intentional attack to sabotage Iran’s nuclear program, it is likely that this was primarily an Israeli operation, possibly done in coordination with local Iranian opposition groups, and quite possibly also coordinated or even jointly executed with, but not primarily led, by the United States.  In my opinion, Israel would not have conducted these attacks without at least informing the United States.

Explosion reportedly damages power plant in Iran, the latest in series of blasts

Incident in city of Ahvaz in southwest follows mysterious explosions at nuclear facility and site near Tehran, which prompted regime to issue warning to Israel and US

An explosion reportedly damaged a power plant in the Iranian city of Ahvaz on Saturday, the latest in a series of mysterious blasts in the country that prompted Iran to issue a warning to Israel and the US earlier this week.

Persian and Arabic media reported an explosion and fire at the Zargan power plant in Ahvaz in Iran’s southwest, near the Persian Gulf and the Iraqi border.

Videos posted online showed a column of smoke at the facility and workers filing past a fire truck.

Iran’s IRNA news agency later reported that the fire at the plant had been brought under control. It said the blaze was ignited when a transformer exploded.

Mohammad Hafezi, the power plant’s health and safety manager, told IRNA the cause of the fire was under investigation.

A few hours later on Saturday, IRNA said a chlorine gas leak at a petrochemical center in southeast Iran sickened 70 workers.

Most of the workers at the Karun petrochemical center in the city of Mahshahr in southeast Khuzestan province were released after undergoing medical treatment.

The two incidents came after an explosion damaged Iran’s Natanz nuclear facility on Thursday, and last week a large blast was felt in Tehran, apparently caused by an explosion at the Parchin military complex, which defense analysts believe holds an underground tunnel system and missile production facilities.

An Israeli TV report Friday night said that Israel was bracing for a possible Iranian retaliation as officials in Tehran suggested on Friday that the mystery fire and explosion at Natanz could have been caused by an Israeli cyberattack.

The report said the attack “destroyed” a laboratory where Iran was developing advanced centrifuges for faster uranium enrichment, and a Kuwaiti report quoted an unnamed source assessing that the strike set back the Iranian nuclear program by two months.

Three Iranian officials told the Reuters news agency they believed the incident at the Natanz enrichment facility early Thursday was the result of a cyberattack, and two of them said Israel could have been behind it, but offered no evidence.

Asked about reports of the incident at a press conference Thursday evening, Prime Minister Benjamin Netanyahu brushed aside the question: “I don’t address these issues,” he said.

But Amos Yadlin, the head of the Institute for National Security Studies, and a former head of IDF military intelligence, tweeted Friday that, “According to foreign sources, it appears that the prime minister focused this week on Iran rather than [his plan for West Bank] annexation. This is the policy I’ve been recommending in the last few weeks.”

Added Yadlin: “If Israel is accused by official sources then we need to be operationally prepared for the possibility of an Iranian reaction (through cyber, firing missiles from Syria or a terror attack overseas).”

Officially, Iran reported an “accident” occurred Thursday at the Natanz nuclear complex in central Iran, saying there were no casualties or radioactive pollution. But top generals also said Iran would respond if the incident turned out to be a cyberattack.

Israel’s Channel 13 TV military analyst Alon Ben-David said Friday evening that the attack hit “the facility where Iran develops more advanced centrifuges — what are meant to be the next stage of the nuclear program, to produce enriched uranium at a far faster rate. That facility yesterday took a substantial hit; the explosion destroyed this lab.

“Those were centrifuges that were supposed to be installed underground at the Natanz facility; they were intended to replace the old centrifuges and produce a lot more enriched uranium, a lot more quickly,” he added. “They suffered a blow. It has to be assumed that at some stage, they will want to retaliate.”

Ben-David said Israel was “bracing” for an Iranian response, likely via a cyberattack. In an April cyberattack attributed by western intelligence officials to Iran, an attempt was made to increase chlorine levels in water flowing to residential Israeli areas.

Hours after the Natanz fire and reported explosion on Thursday, Iran’s state news agency IRNA published an editorial warning that “if there are signs of hostile countries crossing Iran’s red lines in any way, especially the Zionist regime (Israel) and the United States, Iran’s strategy to confront the new situation must be fundamentally reconsidered.”

IRNA also reported that unnamed Israeli social media accounts had claimed the Jewish state was responsible for the “sabotage attempts.” It stressed that Iran had tried “to prevent escalations and unpredictable situations while defending its position and national interests.”

Natanz, located some 250 kilometers (155 miles) south of Tehran, includes underground facilities buried under some 7.6 meters (25 feet) of concrete, which offers protection from airstrikes.

There was “no nuclear material (at the damaged warehouse) and no potential of pollution,” the spokesman for Iran’s Atomic Energy Organization Behrouz Kamalvandi told state television.

Kamalvandi said no radioactive material or personnel were present at the warehouse within the Natanz site in central Iran, one of the country’s main uranium enrichment plants.

The Iranian Atomic Energy Organization released a photo purportedly from the site, showing a one-story building with a damaged roof, walls apparently blackened by fire and doors hanging off their hinges as if blown out from the inside.

The Fars news agency, which is close to the country’s ultra-conservatives, initially reported that the Parchin blast last week was caused by “an industrial gas tank explosion” near a facility belonging to the defense ministry. It cited an “informed source” and said the site of the incident was not related to the military.

However, this was largely disregarded by defense analysts as satellite photographs of the Parchin military complex emerged showing large amounts of damage at the site.

Later, Iranian Defense Ministry spokesman Davood Abdi blamed the blast on leaking gas that he did not identify and said no one was killed in the explosion.

Satellite photos of the area, some 20 kilometers (12.5 miles) east of downtown Tehran, showed hundreds of meters (yards) of charred scrubland not seen in images of the area taken in the weeks ahead of the incident. The building near the char marks resembled the facility seen in the state TV footage.

The gas storage area sits near what analysts describe as Iran’s Khojir missile facility. The explosion appears to have struck a facility for the Shahid Bakeri Industrial Group, which makes solid-propellant rockets, said Fabian Hinz, a research associate at the Middlebury Institute of International Studies at Monterey.

The Washington-based Center for Strategic and International Studies identified Khojir as the “site of numerous tunnels, some suspected of use for arms assembly.” Large industrial buildings at the site visible from satellite photographs also suggest missile assembly being conducted there.

Iranian officials themselves also identified the site as being home to a military base where the International Atomic Energy Agency previously said it suspects Iran conducted tests of explosive triggers that could be used in nuclear weapons.

Iran long has denied seeking nuclear weapons, though the IAEA previously said Iran had done work in “support of a possible military dimension to its nuclear program” that largely halted in late 2003.

Western concerns over the Iranian atomic program led to sanctions and eventually to Tehran’s 2015 nuclear deal with world powers. The US under President Donald Trump unilaterally withdrew from the accord in May 2018, leading to a series of escalating attacks between Iran and the US, and to Tehran abandoning the deal’s production limits.

Kuwait’s Al-Jarida newspaper, which covers security incidents and sometimes alleges Israeli involvement, says that Israel carried out a cyber attack on the Natanz nuclear facility on Thursday. The incident has been downplayed by Iran but experts say that a sensitive warehouse that deals with centrifuges was damaged.

According to the report a source informed Al-Jarida that a cyber attack hit the facility. The report linked this to an earlier cyber attack on Israeli water infrastructure that Iran allegedly carried out and then another cyber attack on an Iranian port in May. It also links the Natanz cyber attack to the earlier Stuxnet computer worm attack in 2010.

These are coordinated sabotage operations, according to the newspaper. The Natanz incident explosion and another explosion near Parchin targeted UF6 gas storage that was used for uranium enrichment. This is uranium hexafluoride gas.

In November, 2019 Iran unveiled the production and injection of the gas into IR-6 centrifuges. These are the advanced centrifuges Iran has increased at Natanz. The Atomic Energy Organization of Iran (AEOI)’s Ali Akbar Salehi has spoken openly about the gas and the new centrifuges. Iran added around 30 of these IR-6 centrifuges to Natanz in November 2019, making at least 60 in total at the site.

The Kuwaiti paper argues that Iran has now lost 80% of its stock of this gas. “This is likely to be an electronic attack on the computer network that controls the storage compression tanks. Iran will need about two months to compensate for the gas that was lost.”

The Natanz explosion led to a “crack in the reactor building. Specialized groups went to the reactor to discover whether there was leakage in radioactive materials.” Iran says there was no leak at the site.

Israel is reportedly bracing for a possible Iranian retaliation as officials in Tehran suggested on Friday that a mystery fire and explosion at a top-secret nuclear complex could have been caused by an Israeli cyberattack.

An Israeli TV report Friday night said the attack “destroyed” a laboratory where Iran was developing advanced centrifuges for faster uranium enrichment, and a Kuwaiti report quoted an unnamed source assessing that the strike set back the Iranian nuclear program by two months.

Three Iranian officials told the Reuters news agency they believed the incident at the Natanz enrichment facility early Thursday was the result of a cyberattack, and two of them said Israel could have been behind it, but offered no evidence.

Asked about reports of the incident at a press conference Thursday evening, Israel’s Prime Minister Benjamin Netanyahu brushed aside the question: “I don’t address these issues,” he said.

But Amos Yadlin, the head of the Institute for National Security Studies, and a former head of IDF military intelligence, tweeted Friday that, “According to foreign sources, it appears that the prime minister focused this week on Iran rather than [his plan for West Bank] annexation. This is the policy I’ve been recommending in the last few weeks.”

Added Yadlin: “If Israel is accused by official sources then we need to be operationally prepared for the possibility of an Iranian reaction (through cyber, firing missiles from Syria or a terror attack overseas).”

Officially, Iran reported an “accident” occurred Thursday at the Natanz nuclear complex in central Iran, saying there were no casualties or radioactive pollution. But top generals also said Iran would respond if the incident turned out to be a cyberattack.

“If it is proven that our country has been attacked by cyberattacks, we will respond,” warned Gen. Gholam Reza Jalali, the head of Iran’s military unit in charge of combating sabotage, according to a report late Thursday by the Mizan news agency.

Israel’s Channel 13 TV military analyst Alon Ben-David said Friday evening that the attack hit “the facility where Iran develops more advanced centrifuges — what are meant to be the next stage of the nuclear program, to produce enriched uranium at a far faster rate. That facility yesterday took a substantial hit; the explosion destroyed this lab.

“Those were centrifuges that were supposed to be installed underground at the Natanz facility; they were intended to replace the old centrifuges and produce a lot more enriched uranium, a lot more quickly,” he aded. “They suffered a blow. It has to be assumed that at some stage, they will want to retaliate.”

Ben-David said Israel was “bracing” for an Iranian response, likely via a cyberattack. In an April cyberattack attributed by western intelligence officials to Iran, an attempt was made to increase chlorine levels in water flowing to residential Israeli areas.

Hours after the Natanz fire and reported explosion on Thursday, Iran’s state news agency IRNA published an editorial warning that “if there are signs of hostile countries crossing Iran’s red lines in any way, especially the Zionist regime (Israel) and the United States, Iran’s strategy to confront the new situation must be fundamentally reconsidered.”

IRNA also reported that unnamed Israeli social media accounts had claimed the Jewish state was responsible for the “sabotage attempts.”

It stressed that Iran had tried “to prevent escalations and unpredictable situations while defending its position and national interests.”

Natanz, located some 250 kilometers (155 miles) south of Tehran, includes underground facilities buried under some 7.6 meters (25 feet) of concrete, which offers protection from airstrikes.

There was “no nuclear material (at the damaged warehouse) and no potential of pollution,” the spokesman for Iran’s Atomic Energy Organisation Behrouz Kamalvandi told state television.

Kamalvandi said no radioactive material or personnel were present at the warehouse within the Natanz site in central Iran, one of the country’s main uranium enrichment plants.

He noted that the cause was being investigated, and said it had caused “some structural damage” without specifying the nature of the accident.

The Iranian Atomic Energy Organization released a photo purportedly from the site, showing a one-story building with a damaged roof, walls apparently blackened by fire and doors hanging off their hinges as if blown out from the inside.

The next stage of the nuclear program

Two US-based analysts who spoke to The Associated Press on Thursday, relying on released pictures and satellite images, identified the affected building as Natanz’s new Iran Centrifuge Assembly Center.

On Friday, a Kuwaiti newspaper reported Israel was responsible for two recent blasts at Iranian facilities — the one at Natanz, and another at a missile production site days earlier.

The Al-Jareeda daily cited an unnamed senior source as saying that an Israeli cyberattack caused a fire and explosion at Natanz.

According to the source, this was expected to set back Iran’s nuclear enrichment program by approximately two months.

The newspaper also reported that last Friday Israeli F-35 stealth fighter jets bombed a site located in the area of Parchin, which is believed to house a missile production complex — an area of particular concern for the Jewish state, in light of the large number and increasing sophistication of missiles and rockets in the arsenals of Iranian proxies, notably Lebanon’s Hezbollah.

Neither of these claims were confirmed by Israeli officials, who have been mum on the reports.

The reported Israeli strikes followed an alleged Iranian attempt to hack into Israel’s water infrastructure in April, an effort that was thwarted by Israeli cyber defenses, but if successful could have introduced dangerous levels of chlorine into the Israeli water supply and otherwise seriously interrupted the flow of water throughout the country.

Ultimately, the alleged Iranian cyberattack caused minimal issues, according to Israeli officials.

The alleged Israeli attacks also came amid an ongoing campaign of so-called maximum pressure by the United States in the form of crushing sanctions on Iran and Iranian officials.

The BBC’s Persian service said it received an email from a group identifying itself as the “Cheetahs of the Homeland” claiming responsibility for the attack. The email was received prior to the announcement of the Natanz fire.

The group, which claimed to be dissident members of Iran’s security forces, had never been heard of before by Iran experts and the claim could not be immediately authenticated by The Associated Press.

The site of the fire corresponds to a newly opened centrifuge production facility, said Fabian Hinz, a researcher at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies in Monterey, California. He said he relied on satellite images and a state TV program on the facility to locate the building, which sits in Natanz’s northwest corner.

David Albright of the Institute for Science and International Security similarly said the fire struck the production facility. His institute previously wrote a report on the new plant, identifying it from satellite pictures while it was under construction and later built.

Iranian nuclear officials did not respond to a request for comment about the analysts’ comments.

Last Friday, a large blast was felt in Tehran, apparently caused by an explosion at the Parchin military complex, which defense analysts believe hold an underground tunnel system and missile production facilities.

According to the al-Jareeda report on Friday, that explosion was caused by missiles dropped by a number of Israeli F-35 stealth fighter jets. The newspaper reported that the aircraft took off from southern Israel and carried out the bombing run without the need to refuel.

The Fars news agency, which is close to the country’s ultra-conservatives, initially reported that Parchin blast was caused by “an industrial gas tank explosion” near a facility belonging to the defense ministry. It cited an “informed source” and said the site of the incident was not related to the military.

However, this was largely disregarded by defense analysts as satellite photographs of the Parchin military complex emerged showing large amounts of damage at the site.

Later, Iranian Defense Ministry spokesman Davood Abdi blamed the blast on a leaking gas that he did not identify and said no one was killed in the explosion.

Satellite photos of the area, some 20 kilometers (12.5 miles) east of downtown Tehran, showed hundreds of meters (yards) of charred scrubland not seen in images of the area taken in the weeks ahead of the incident. The building near the char marks resembled the facility seen in the state TV footage.

The gas storage area sits near what analysts describe as Iran’s Khojir missile facility. The explosion appears to have struck a facility for the Shahid Bakeri Industrial Group, which makes solid-propellant rockets, said Fabian Hinz.

The Washington-based Center for Strategic and International Studies identified Khojir as the “site of numerous tunnels, some suspected of use for arms assembly.” Large industrial buildings at the site visible from satellite photographs also suggest missile assembly being conducted there.

Iranian officials themselves also identified the site as being home to a military base where the International Atomic Energy Agency previously said it suspects Iran conducted tests of explosive triggers that could be used in nuclear weapons. Iran long has denied seeking nuclear weapons, though the IAEA previously said Iran had done work in “support of a possible military dimension to its nuclear program” that largely halted in late 2003.

Western concerns over the Iranian atomic program led to sanctions and eventually to Tehran’s 2015 nuclear deal with world powers. The US under President Donald Trump unilaterally withdrew from the accord in May 2018, leading to a series of escalating attacks between Iran and the US, and to Tehran abandoning the deal’s production limits.

Iran nuclear site fire hit centrifuge facility, analysts say

Whoopsie!

A fire and an explosion struck a centrifuge production plant above Iran’s underground Natanz nuclear enrichment facility early Thursday, analysts said, one of the most-tightly guarded sites in all of the Islamic Republic after earlier acts of sabotage there.

The Atomic Energy Organization of Iran sought to downplay the fire, calling it an “incident” that only affected an under-construction “industrial shed,” spokesman Behrouz Kamalvandi said. However, both Kamalvandi and Iranian nuclear chief Ali Akbar Salehi rushed after the fire to Natanz, a facility earlier targeted by the Stuxnet computer virus and built underground to withstand enemy airstrikes.

The fire threatened to rekindle wider tensions across the Middle East, similar to the escalation in January after a U.S. drone strike killed a top Iranian general in Baghdad and Tehran launched a retaliatory ballistic missile attack targeting American forces in Iraq.

While offering no cause for Thursday’s blaze, Iran’s state-run IRNA news agency published a commentary addressing the possibility of sabotage by enemy nations such as Israel and the U.S. following other recent explosions in the country.

“The Islamic Republic of Iran has so far has tried to prevent intensifying crises and the formation of unpredictable conditions and situations,” the commentary said. But ”the crossing of red lines of the Islamic Republic of Iran by hostile countries, especially the Zionist regime and the U.S., means that strategy … should be revised.”

The fire began around 2 a.m. local time in the northwest corner of the Natanz compound in Iran’s central Isfahan province, according to data collected by a U.S. National Oceanic and Atmospheric Administration satellite that tracks fires from space.

Images later released by Iranian state media show a two-story brick building with scorch marks and its roof apparently destroyed. Debris on the ground and a door that looked blown off its hinges suggested an explosion accompanied the blaze.

“There are physical and financial damages and we are investigating to assess,” Kamalvandi told Iranian state television. “Furthermore, there has been no interruption in the work of the enrichment site. Thank God, the site is continuing its work as before.”

In Washington, the State Department said that U.S. officials were “monitoring reports of a fire at an Iranian nuclear facility.”

“This incident serves as another reminder of how the Iranian regime continues to prioritize its misguided nuclear program to the detriment of the Iranian people’s needs,” it said.

The site of the fire corresponds to a newly opened centrifuge production facility, said Fabian Hinz, a researcher at the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies in Monterey, California.

Hinz said he relied on satellite images and a state TV program on the facility to locate the building, which sits in Natanz’s northwest corner.

David Albright of the Institute for Science and International Security similarly said the fire struck the production facility. His institute previously wrote a report on the new plant, identifying it from satellite pictures while it was under construction and later built.

Iranian nuclear officials did not respond to a request for comment about the analysts’ comments. However, any damage to the facility would be a major setback, said Hinz, who called the fire “very, very suspicious.”

“It would delay the advancement of the centrifuge technology quite a bit at Natanz,” Hinz said. “Once you have done your research and development, you can’t undo that research and development. Targeting them would be very useful” for Iran’s adversaries.

Natanz, also known as the Pilot Fuel Enrichment Plant, is among the sites now monitored by the International Atomic Energy Agency after Iran’s 2015 nuclear deal with world powers. That deal saw Iran agree to limit its uranium enrichment in exchange for the lifting of economic sanctions.

The IAEA said in a statement it was aware of reports of the fire. “We currently anticipate no impact on the IAEA’s safeguards verification activities,” the Vienna-based agency said.

Natanz became a flashpoint for Western fears about Iran’s nuclear program in 2002, when satellite photos showed Iran building an underground facility at the site, some 200 kilometers (125 miles) south of the capital, Tehran. In 2003, the IAEA visited Natanz, which Iran said would house centrifuges for its nuclear program, buried under some 7.6 meters (25 feet) of concrete.

Natanz today hosts the country’s main uranium enrichment facility. In its long underground halls, centrifuges rapidly spin uranium hexafluoride gas to enrich uranium. Currently, the IAEA says Iran enriches uranium to about 4.5% purity — above the terms of the nuclear deal but far below weapons-grade levels of 90%. Workers there also have conducted tests on advanced centrifuges, according to the IAEA.

The U.S. under President Donald Trump unilaterally withdrew from the nuclear deal in May 2018, setting up months of tensions between Tehran and Washington. Iran now is breaking all the production limits set by the deal, but still allows IAEA inspectors and cameras to watch its nuclear sites.

Natanz remains of particular concern to Tehran as it has been targeted for sabotage before. The Stuxnet malware, widely believed to be an American and Israeli creation, disrupted and destroyed centrifuges at Natanz amid the height of Western concerns over Iran’s nuclear program.

Satellite photos show an explosion last Friday that rattled Iran’s capital came from an area in its eastern mountains that analysts believe hides an underground tunnel system and missile production sites. Iran has blamed the blast on a gas leak in what it describes a “public area.”

Yoel Guzansky, a senior fellow at Israel’s Institute for National Security Studies and former Iran analyst for the prime minister’s office, said he didn’t know if there was an active sabotage campaign targeting Tehran. However, he said the series of explosions in Iran feel like “more than a coincidence.”

“Theoretically speaking, Israel, the U.S. and others have an interest to stop this Iran nuclear clock or at least show Iran there’s a price in going that way,” he said. “If Iran won’t stop, we might see more accidents in Iran.”

Late Thursday, the BBC’s Persian service said it received an email prior to the announcement of the Natanz fire from a group identifying itself as the Cheetahs of the Homeland, claiming responsibility for an attack on the centrifuge production facility at Natanz. This group, which claimed to be dissident members of Iran’s security forces, had never been heard of before by Iran experts and the claim could not be immediately authenticated by the AP.
