Iraq is capping off its worst year of violence since the height of the U.S. occupation. According to the United Nations, more than 7,150 civilians and 950 security forces have been killed this year, the highest annual total since 2008. On Monday, at least 13 people were killed in clashes when Iraqi police raided a Sunni protest camp in Anbar province. Protesters had been camped out for a year to protest the marginalization of Sunnis by the Shiite-led government. More than 40 Sunni lawmakers announced their resignations following the raid. Separate attacks across Iraq killed at least 11 other people.
