A suicide car bomb blast killed 18 people, including 10 policemen, and wounded 28 others in an attack in the northern Iraqi city of Kirkuk on Tuesday, police and doctors at Kirkuk's main hospital said.
The bomber detonated his explosives-laden car near the police vehicles on the main road leading south out of Kirkuk to Baghdad. Ten of those killed were policemen, Colonel Borhan Tayyib Taha said. Some of the wounded were also policemen, he said.
The US military surrounded the blast site soon after the attack.
