BAGHDAD (Reuters) - Sunni Muslim fighters clashed on Thursday with Iraqi troops trying to regain control of two western cities, in a serious escalation of their confrontation with the Shi'ite-led government of Prime Minister Nuri al-Maliki.
Tension has been running high in the Sunni-dominated province of Anbar since Iraqi police broke up a Sunni protest camp on Monday, leaving at least 13 people dead.
