A car bomb exploded in Iraq's oil-rich northern city, Kirkuk, Monday morning, killing at least 10 people outside a police station.

Police officers were gathered to receive their assignments for the day, when the car bomb was detonated. The explosion damaged nearby buildings and both police and civilians were among the dead and injured.

Iraqi police and emergency workers evacuated the wounded and are digging through the rubble, looking for survivors.

Iraqi police have become a common target for suicide bombers, in recent weeks, and the insurgency has branded them as collaborators with the American-led occupation. More than 300 people have been killed by car bombs, so far this year. Two suicide bombers in the northern town, Irbil, last month killed about 100 people, in simultaneous attacks.
