Meanwhile the U.S. announced on Sunday it would hold off waging another large offensive against the Sunni city of Falluja. Late last week a senior U.S. officer warned that the U.S. was going to turn Falluja into “a killing field in a couple of days.” Instead the U.S. announced it would conduct joint patrols with the US-trained Iraqi Civil Defense Corps. But one captain in the Iraqi force warned the joint patrols will not likely work. He told the Boston Globe '’If people see us walking with the Marines, the mujahideen ’will do one of two things. Either they will wait for us at our homes and shoot us. Or they will shoot us when we're with the Marines. We want the Marines to leave and let us take care of the city.”
