The overrunning of cities in Iraq by al-Qaeda's Iraqi branch in the Sunni heartland of western Anbar provinces is a blow to the Shiite-led government of Prime Minister Nouri al-Malik. 

His government has been struggling to contain discontent among the Sunni minority over Shiite political domination that has flared into increased violence for the past year.

In Fallujah recently, al-Qaeda gunmen sought to win over the population. A militant commander appeared among worshippers holding Friday prayers in the main city street, proclaiming that his fighters were there to defend Sunnis from the government, one resident said.

"We are your brothers from the Islamic State in Iraq and Levant," militants circulating through the city in a stolen police car proclaimed through a loudspeaker, using the name of the al-Qaeda branch. "We are here to protect you from the government. We call on you to cooperate with us."

Government troops, backed by Sunni tribesmen who oppose al-Qaeda, have encircled Fallujah for several days, and have entered parts of the provincial capital Ramadi, also overrun by militants.  

Troops bombarded militant positions outside Fallujah with artillery, a military official said, speaking on condition of anonymity as he was not authorized to release information.

Anbar province, a vast desert area on the borders with Syria and Jordan with an almost entirely Sunni population was the heartland of the Sunni insurgency that rose up against American troops and the Iraqi government after the 2003 U.S.-led invasion that toppled Saddam Hussein.

The insurgency was fueled by anger over the dislodgment of their community from power during Saddam's rule and the rise of Shiites. It was then that al-Qaeda established its branch in the country.

Fallujah became notorious among Americans when insurgents in 2004 killed four American security contractors and hung their burned bodies from a bridge. It, the provincial capital Ramadi and other cities were repeatedly battlegrounds for the following years, as sectarian bloodshed mounted, with Shiite militias killing Sunni.

But 2013 has been the deadliest year since, with a resurgence of violence after al-Maliki's government in April violently broke up a protest by Sunnis against discrimination by Shiite authorities.  Read more:
