BAGHDAD (Reuters)- A suicide car bomb killed five children and six neighborhood patrol volunteers on the outskirts of Baghdad on Monday, an Interior Ministry source said.

The bomber struck a checkpoint manned by neighborhood patrol volunteers near a school in Tarmiya, north of the Iraqi capital.

Seven patrol volunteers were wounded. The child victims were attending the school.

Patrols made up mainly of Sunni Arabs paid by U.S. forces to oppose al Qaeda militants have often been struck by bombers in recent weeks, especially north of the capital, where U.S. forces say militants have regrouped after being pushed from other areas.
