Shin Bet
In October 1995, Shin Bet operatives approached Kamil Hamad. Kamil Hamad demanded money and Israeli identity cards for himself and his wives. After the Shin Bet threatened to inform Hamas of his betrayal, Kamil Hamad agreed to cooperate. Shin Bet agents gave Hamad a cell phone, and told him it was bugged so they could listen in on Ayyash's conversations. They did not tell Hamad that, in addition to eavesdropping devices, it also contained 15 grams of RDX explosive.
