Backed by air power, US forces targeting militants believed to be responsible for the kidnapping of two coalition soldiers raided the main Shi'ite district in Baghdad on Sunday. Iraqi officials said at least 13 people were killed, including women and children.
The US military said troops staged early morning operations in Sadr City, a stronghold of the Mahdi Army militia that is loyal to radical Shi'ite cleric Muqtada al-Sadr.
Iraqi police and hospital officials said helicopters and jet fighters bombed buildings during the 5 a.m. raid in the sprawling district and at least 13 people were killed, including a woman and three children, and 52 were wounded.
Several houses and stores were damaged.
