Iraqi police say a suicide truck bomber has killed at least 15 people and wounded more than 20 at a police station in northern Iraq.

Police say the attack took place Sunday in the mainly Sunni town of Adwar, 20 kilometers south of Tikrit. They say the bomber rammed a truck loaded with hay through the gate of a police station and triggered the blast outside the building.
