Yahya Ayyash - Work For Hamas

Work For Hamas

Ayyash built the bombs used in a number of Hamas suicide attacks: the Mehola Junction bombing, the Afula Bus massacre, the Hadera central station massacre, the Tel Aviv bus 5 massacre, the Egged bus 36 bombing, the Ramat Gan bus 20 bombing, and the Jerusalem bus 26 bombing. As part of a strategic alliance between Hamas and Palestinian Islamic Jihad, Ayyash built the bombs used by Islamic Jihad at the Beit Lid massacre.

Because TNT and other high explosives were generally not available in the Palestinian territories (the West Bank and Gaza strip), Ayyash often used a combination of acetone and detergent, both commonly available household products. When combined, they form acetone peroxide, an explosive known as "Mother of Satan" for its instability.
