Iraqi police say at least 14 people died and dozens of others were wounded in a series of car bombs Sunday in the western city of Ramadi.

The blasts occurred near a provincial government building.

Police and witnesses say the first bomb exploded in the parking lot outside the building.  They say a second bomb exploded when police and rescue workers arrived at the scene.  A third bomb detonated later, but there are few details about that explosion.

It was the third set of deadly bombings in less than a week in Anbar province.

No group immediately claimed responsibility for Sunday's violence.  Al-Qaida often uses secondary bombings as a tactic to kill rescuers and security forces who respond to the primary attack.

Iraq's Anbar province once was an insurgent stronghold.  But violence there greatly decreased after local Sunni tribes sided with the U.S. military in 2006 to fight against al-Qaida.
