Four dead in Iraq shootings

Four security personnel, including two anti-al-Qaida militiamen, have been killed in shootings in north-central Iraq.

Police officials said the first attack took place early today when gunmen in a speeding car killed two fighters and wounded four others at a security checkpoint manned by Sunni Sahwa militiamen in the city of Samarra.

Police also said they found the bodies of two police officers killed by gunshots to the head in a town near the northern city of Mosul, a day after they were kidnapped.

Medical officials confirmed the casualty figures.
