On August 19, 2003 (22 Av 5763), a Hamas suicide bomber sent out by the organization's Hebron cell disguised himself as a Haredi Jew and detonated himself on a No. 2 Egged bus traveling through Jerusalem's Shmuel HaNavi neighborhood. He blew himself up after entering the back door.[2] The double-length bus was crowded with Orthodox Jewish children returning from a visit to the Western Wall. The huge explosion killed 7 children and 16 adults, among them an eight-months-pregnant woman, and injured more than 130 people.
