Yahya Abd-al-Latif 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.

[14] Unable to obtain TNT and other high explosives in the Palestinian territories, Ayyash used readily available household products such as a combination of acetone and detergent.

When police inspected their car, they found it rigged with a bomb—five 12-kilogram (26 lb) gasoline tanks filled to capacity, connected to an acetone peroxide-based detonator.

After evacuating the area, sappers used a robot armed with a shotgun to shoot the detonator in the hopes of defusing it but it blew up, causing a massive explosion.

[18] In October 1995, Kamil Hamad met with Shin Bet operatives, demanding money and Israeli identity cards for himself and his wives.

[21] Israel did not confirm or deny its role in killing Ayyash, which led to rumors and speculation about the extent of Israeli involvement.

[13] 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.

"[23] The Militant, a newsweekly associated with the Socialist Workers Party (United States), reported that "100,000 Palestinians... attended the funeral".

Only a few weeks earlier, a square in Ramallah was named after the Palestinian militant Dalal Mughrabi who directed the 1978 Coastal Road massacre.

Honoring terrorists who have murdered innocent civilians either by official statements or by the dedication of public places hurts peace efforts and must end.

"[28] The PA had previously named streets in Jenin[6] and Beit Lahia as well as square in Jericho in honor of Ayyash.
