Officials say a car bomb explosion in central Iraq has killed three people and wounded 16 others. A police officer says a suicide car bomber drove his explosive-laden car Sunday morning into a police check point in the town of Khalis, killing two civilians and one policeman. He added that 16 other people were wounded. A medical official in a nearby hospital confirmed the causality figures. Both officials spoke on condition of anonymity as they were not authorized to release information. Khalis, a former stronghold of Sunni insurgency, is located about 50 miles (80 kilometers) north of Baghdad.
