Iraqi soldiers monitor a demonstration as residents of the war-torn city of Falluja protest against the present of U.S. forces outside the heavily guarded "Green Zone" in Baghdad, December 18, 2004. The U.S. military said it would allow some residents to return to Falluja, nearly six weeks after an offensive was launched to rid the city west of Baghdad of rebels and despite continued clashes in some districts.
