U.S. and Iraqi troops have intensified their offensive in the northern city of Mosul to retake control of police stations and other government buildings seized by gunmen during the last week.
American helicopters and war planes provided cover as troops struck isolated pockets of resistance. Mosul's bridges are closed, and a curfew remains in effect from 4 p.m. to 6 a.m. (local time).
Many insurgents are believed to have fled to Mosul before U.S. forces began an offensive against the militant stronghold of Fallujah last week.
Meanwhile, in Fallujah, U.S. General George Casey said the week-long operation had been "a very substantial victory."
Much of the city sustained heavy damage during the offensive, and local authorities spent the day collecting the dead from streets, alleyways and buildings.
