U.S. Marines detain a man during a series of raids to hunt arms and guerrilla suspects south of Baghdad December 1, 2004. After a day of intensive sweeps by U.S. and British troops through farms and homes in a fertile stretch of the Euphrates Valley where support for Saddam Hussein was strong, a squad of Marines came under mortar fire close to the river.
