Forty-four Iraqi MPs have announced their resignation over violence in Anbar province, just days after a deadly raid on the home of a Sunni lawmaker in the area. Fighting erupted when police broke up a Sunni Muslim protest camp on Monday, leaving at least 13 people dead, police and medical sources said. The camp has been an irritant to Prime Minister Nouri al-Maliki's Shia-led government since protesters set it up a year ago to demonstrate against what they see as marginalisation of their sect.
