A suicide bombing at the funeral of the son of a tribal leader and anti-Al-Qaeda militiaman killed 12 people and wounded 25 others in central Iraq on Sunday, officials said.

The funeral had been for Mudher al-Shallal al-Araki, who was killed in a roadside bombing near his family's home in the restive city of Baquba, north of Baghdad, the previous evening, according to a police colonel and Dr Hussein al-Tamimi from a nearby hospital.

The blast struck at the graveyard where the procession, which included relatives and members of the family's tribe, was due to bury the body.
