Five people were killed when a suicide bomber drove a minivan packed with up to half a tonne of explosives into a house where Sunni tribal leaders opposed to al Qaeda were meeting north of Baghdad on Sunday, police said.
Police sources in Taji, about 20 km (12 miles) north of the Iraqi capital, said the five killed were all local Sunni tribal chiefs. Twelve others were wounded. A US military unit at the scene later said tribal leaders were not among those killed and that the attack was carried out by two suicide bombers, who were among the five dead.
