The 2007 Yazidi communities bombings occurred at around 8pm local time on August 14, 2007, when four co-ordinated suicide bomb attacks detonated in the Yazidi towns of Kahtaniya and Jazeera (Siba Sheikh Khidir), near Mosul. Iraqi Red Crescent's estimates say the bombs killed 796 and wounded 1,562 people, making this the Iraq War's most deadly car bomb attack during the period of major American combat operations. It was also the second deadliest act of terrorism in history, following only behind the September 11 attacks in the United States.
