debkafile reports exclusively that Egyptian security detained Hamas’ head of security Mohammad Dababesh at Cairo international airport Friday, Sept. 17, the first high-ranking Palestinian held for questioning by Egyptian security. It is not clear whether Dababesh was on his way back to or from the Gaza Strip. Our sources report that he is no doubt being grilled on the Grad missile attack launched against Eilat and Aqaba from Sinai on Aug. 3, in which two Egyptian border posts were destroyed.
He is senior enough in Hamas  to have been in on that incident and knowledgable about the West Bank cells responsible for murdering four Israelis near Hebron on Aug. 30 and injuring a couple at the Rimonim junction two days later. The Egyptian authorities may therefore have acted to nab Dababesh on a tip-off from Israel.
debkafile reported earlier Friday, that a joint Israeli military-Shin Bet unit raided the Nur a-Shams camp in the West Bank town of Tulkarm and killed Iyad Assad Ahmad Abu Shalbaya, identified as deputy chief of the West Bank Hamas network responsible for those murders.
This was Israel’s first major operation against known Palestinian terrorist chiefs in some years. It was carried out after Palestinian security forces failed to catch up with the perpetrators.
Shalbaya was caught in the dragnet the IDF and undercover units have cast across the northern and southern West Bank areas since early this week to thwart the wave of terror Hamas threatened for the purpose of derailing talks with the Palestinians and hitting Israel over the Jewish Yom Kippur festival which begins Friday night.
