The Iraq government has lost control of the strategic city of Falluja, west of Baghdad, to al-Qaeda-linked militants.
Fighting there erupted after troops broke up a protest camp by Sunni Arabs in the city of Ramadi on Monday.
Prime Minister Nouri Al Maliki has promised there will be no retreat until what he calls a gang of terrorists are eliminated.
