Suicide bomb at Iraq neighborhood patrol kills 4

BAGHDAD (Reuters) - A suicide bomber wearing an explosive vest killed four Iraqi neighborhood patrol volunteers at a checkpoint on Baghdad's northern outskirts on Monday, police said.

Two volunteers were also wounded in the attack, they said.

neighborhood patrols, mainly made up of Sunni Arabs paid by U.S. forces to oppose al Qaeda Sunni Arab militants, have frequently been targeted by bombers in recent weeks.
