Officials say a car bomb has hit a patrol in Mosul, one of three attacks in the northern Iraqi city that left five dead. A police officer says the car bomb went off early Sunday morning at a house as a joint army-police unit was conducting door-to-door searches, killing two policemen and one soldier. He says 21 people, including 4 civilians, were wounded. Downtown, militants gunned down a policeman in his car. Authorities also found a body floating in the Tigris river, shot at close range with the hands tied behind the back, according to a report of the Associated Press.
