On Friday, July 4, 1975, a refrigerator that had five kilograms of explosives packed into its sides exploded on Zion Square, a main square leading to Ben Yehuda Street and Jaffa Road. Fifteen people were killed and 77 injured in the attack. Ahmad el-Sukar, who was responsible for placing the bomb, was released from Israeli prison in 2003 as a gesture to Arafat.
