About Yahya Ayyash
Yahya Ayyash (Arabic: يحيى عياش, romanized: Yaḥyā ʿAyyāš, pronounced [jaħjaː ʕajːaʃ]; 6 March 1966 – 5 January 1996) was the chief bombmaker of Hamas and the leader of the West Bank battalion of the Izz ad-Din al-Qassam Brigades. In that capacity, he earned the nickname "the Engineer" (Arabic: المهندس, romanized: al-Muhandis). Ayyash is credited with advancing the technique of suicide bombings against Israel by Palestinian militant groups. The bombings he orchestrated killed approximately 90 Israelis, many of them civilians. He was assassinated by the Shin Bet on January 5, 1996, through a booby-trapped mobile phone. Ayyash is celebrated by local Palestinian communities who have named streets and other locales in his honor. His name was also given to the rocket Ayyash-250 produced by Hamas. The first of these took place shortly after the end of the 40-day mourning period for Ayyash and the cell that claimed responsibility called itself "Disciples of the martyr Yahya 'Ayyash", stating it was a revenge attack for his assassination. Kamil Hamad disappeared and it is rumored that he received US$1 million, a fake passport and a visa to the US.
