At least 21 insurgents have been killed in central Iraq after a car bomb was detonated accidentally, officials say.
The explosion occurred in the early afternoon on a desert road, about 20km (12 miles) from the city of Samarra, security sources told the BBC.
The explosives-filled vehicle was being escorted from the insurgents' compound to a main road when it blew up.
The area around the mainly Sunni city of Samarra, in Salah al-Din province, has long been an insurgent stronghold.
