Shiite politicians demanded changes in the Iraqi government Sunday, accusing a Sunni Arab party in the coalition of ties to terrorism after a bodyguard of its leader was arrested on suspicion of planning bomb attacks.
The dispute threatened a sectarian crisis within the national unity government of Prime Minister Nouri al-Maliki, which is struggling to contain spiraling Shiite-Sunni killings that the U.S. ambassador said have surpassed Sunni insurgent attacks in deadliness.
After the bodyguard's arrest, an unprecedented surprise curfew was imposed on Baghdad on Saturday, preventing pedestrians as well as vehicle traffic. The curfew was lifted early Sunday.
