BAGHDAD — Staggered explosions killed 23 people — 13 of them policemen — and injured the governor of Anbar today, Iraqi officials said, the worst violence in months to hit the western province as it struggles to stamp out the remnants of the al-Qaida insurgency.

Anbar is strategically important because it was once the heartland of support for al-Qaida linked militants before American officials paid Iraqi fighters to join a pro-government force. The governor is the most senior Sunni leader to be attacked since then.

Police official Lt. Col. Imad al-Fahdawi said two bombs exploded in Anbar's capital of Ramadi, 70 miles west of Baghdad. He said a suicide bomber in a car caused the first blast near a checkpoint on the main road near the provincial administration buildings.

Gov. Qassim al-Fahdawi, the deputy police chief and other officials came to inspect the damage, the police official said, when a suicide bomber on foot detonated a vest full of explosives nearby.

The deputy police chief was killed and the governor and other officials wounded, al-Fahdawi said. Police have put a curfew in place, he added.

Another police official said the provincial police commander was wounded. The police official spoke on condition of anonymity because he was not authorized to speak to the media.

Dr. Ahmed Abid Mohammed said 23 people were killed and 57 injured. He said the governor had suffered burns on his face, injuries to his abdomen and other areas.
