BAQUBA, Iraq: The governor of Iraq's restive Diyala province was wounded in a suicide car bombing on Saturday that killed two of his guards and wounded six more, a police officer and a doctor said.

The bomber detonated an explosives-laden vehicle at Governor Omar al-Humairi's house in Baquba, the capital of Diyala province, a police lieutenant colonel said.

Humairi, a member of the Iraqi Islamic Party, became governor of Diyala, a province that suffers frequent attacks by militants, in September.

No group has yet claimed responsibility for the attack, but Sunni militants linked to the Al-Qaeda franchise in Iraq often target the security forces and government officials, and suicide bombings are a hallmark of the group.
