Two suicide bombers blew themselves up Thursday in a crowded outdoor market in a Shi'ite city south of Baghdad, killing 10 people and wounding 15, police said. The attackers strolled into the Maktabat outdoor market in the center of Hillah, 95 kilometers south of Baghdad, about 6 p.m. as shoppers were buying food for their evening meals. Police thought one of the men appeared suspicious and stopped him, according to police. The bomber then detonated his explosives. The second attacker who was walking behind him then set off his own explosives belt, police added. Hillah was the scene of one of the deadliest attacks in the Iraq war, when a suicide car bomber killed 125 people on February 28, 2005.
