BAGHDAD: Staggered explosions killed 23 people Wednesday including the governor of Anbar, Iraqi officials said, in the latest violence to roil a turbulent province that is still struggling to stamp out the remnants of the al-Qaida insurgency. The western province of 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.
