A suicide bomber killed about 30 people and wounded dozens during a Muslim funeral at Miqdadiya, 100 km (60 miles) northeast of Baghdad, on Wednesday, an Iraqi security official said. Mourners took cover in the cemetery, under fire from mortars and automatic weapons. Then a bomber wearing an explosive vest blew up among them, the official said. The death toll was provisional. If confirmed it would be the bloodiest attack since a largely peaceful election on Dec. 15, according to a report of Reuters. The funeral was for a victim or victims of an assassination attempt on Tuesday on a local leader of the Dawa party of Prime Minister Ibrahim al-Jaafari. The leader was badly wounded in that attack and his son and a bodyguard were killed. It was not entirely clear who was being buried during Wednesday's assault.
