From Haaretz, :
The Shin Bet security services and the Israel Defense Forces said Tuesday they have in recent weeks arrested 16 residents of Bethlehem who are suspected of having planned a series of large-scale terror attacks in Jerusalem.
The cells allegedly planned to launch two pairs of suicide bombers to the Mea She’arim neighborhood in the capital, and are said to have planned a terror attack using an explosive-laden ambulance. Also attributed to one of the cells is a plan to attack a bus carrying worshippers to Rachel’s Tomb near Bethlehem.
Based on details released on Tuesday by security forces, Hamas was to provide the suicide bombers for the missions, while Islamic Jihad was supposed to supply the explosive devices. Some of those arrested, including the would-be suicide bombers, served in the Palestinian national security services. Among those arrested is Hamed Dar’awi, an active member in the PA’s national security services, who is said to have been the mastermind for the ambulance attack.
