An Iraqi civilian was killed and three policemen wounded when a car bomb went off near a police patrol on Sunday, a well-informed police source told Xinhua.

"A car bomb parking near the al-Amana Garage in the Wahda district, detonated shortly after 10:00 a.m. (0600 GMT) near a passing police patrol," the source said on condition of anonymity.

The blast killed a civilian and damaged a police vehicle wounding three policemen aboard, he said.

Insurgents frequently attack Iraqi police and army forces, accusing them of collaborating with U.S. occupation forces.
