U.S. troops discovered eight more bodies in the restive northern Iraqi city of Mosul (search), bringing the number of bodies found there since Nov. 10 to more than 150, the U.S. military said Tuesday.

Initially peaceful after the U.S.-led invasion in Iraq (search), Mosul has become a worrisome trouble spot since the American and Iraqi militaries invaded the insurgent stronghold of Fallujah in November. Soon after, Mosul witnessed an uprising that saw militants overpowering police, looting or burning police stations.

Since then, police say insurgents have been targeting security forces and police there in a bid to strengthen their grip. U.S. military spokesman Lt. Col. Paul Hastings said the number of bodies found so far was more than 150, though it wasn't known if all were affiliated with the police or Iraqi National Guard (search).

On Sunday, seven bodies with gunshot wounds were found in a western Mosul neighborhood, and an eighth was found separately, Hastings said. Their identities were not known, but the body found alone had a sign believed left by insurgents suggesting the man was from the Iraqi National Guard.

Separately, a police officer was wounded when gunmen shot at his car in western Mosul on Monday, police Capt. Ahmed Khalil said.
