A suicide truck bomber targeted a police station in the northern city of Kirkuk on Monday, killing at least 13 people and wounding dozens, including many children from a nearby school, police said. The attacker rammed the truck into the concrete blast barriers surrounding the back of the compound at about 11:30 a.m., detonating his explosives, which were hidden under a load of flour, local police spokesman Brig. Gen. Sarhat Qadir said. He said 13 people were killed and 137 wounded. He also said at least 20 children who had been playing outside at a nearby school were among the casualties, although he could not provide a breakdown.
