A provincial official says a bomb explosion has killed the police chief of Iraq's restive Anbar province.

Councilman Faleh al-Issawi says the bomb went off Sunday morning near a convoy including Brig. Gen. Ahmed al-Dulaimi in the vast province west of Baghdad. The convoy had been traveling through an area to the north of the provincial capital, Ramadi.

It was not immediately clear if others were killed. The councilman said Iraqi security forces had recaptured the area from the militants a day earlier.

Anbar has seen a growing Sunni-led insurgency since early this year. Sunni armed groups led by an al-Qaida breakaway group, known as Islamic State, have fully controlled the city of Fallujah, parts of Ramadi and rural areas.

There was no immediate claim of responsibility.
