iraqi protest ABU GHRAIB, Iraq (Reuters) - Hundreds of Iraqis marched on Wednesday outside the walls of the military jail in Iraq where U.S. soldiers photographed themselves abusing Iraqi prisoners, and demanded the release of jailed relatives. Protesters carrying Iraqi flags and placards reading in English "You have given a bad impression of America and Christians," gathered at the Abu Ghraib prison, infamous for torture under deposed Iraqi strongman Saddam Hussein. Images released last week of U.S. troops abusing Iraqis in the jail have inflamed sentiment against the U.S.-led occupation of the country and left Washington scrambling to repair its image with Iraqis ahead of a formal handover of sovereignty. Relatives of the nearly 4,000 Abu Ghraib prisoners who are among about 10,000 Iraqis held by occupying troops demanded they be set free immediately. Some said the images of soldiers forcing Iraqis to pose nude and simulate sex acts would draw retribution. "They have taken five of my children. It's a crime," screamed one woman at a checkpoint outside the prison on the western outskirts of Baghdad, surrounded by blast barriers, razor wire and U.S. machine-gun posts atop the walls. "These acts demand revenge and we hold you completely responsible," said a representative of the Association of Muslim Clerics, a Sunni Muslim group which has helped organize some of the protests which regularly demand the release of detainees. The U.S. military, which has acknowledged at least two Iraqi detainees have been murdered by soldiers or contractors, has put a general who once ran its Guantanamo Bay prison camp in charge of reforming Iraq's military jails.
