Meanwhile, thousands of supporters of Moqtada al-Sadr marched in Baghdad on Saturday to denounce the U.S. presence in Iraq and call for a speedy trial of Saddam Hussein on the second anniversary of his overthrow. Chanting "No, no to the occupiers", thousands of young and old men gathered in the poor Shi'ite district of Sadr City to begin a planned peaceful march to Firdos Square. Iraqi security forces shut down central Baghdad ahead of the demonstration, but were not expecting problems. "We're quite relaxed about it," said Sabah Kadhim, a spokesman for the Interior Ministry, which is overseeing security arrangements. "The demonstration is supporting what the Iraqi people and the Iraqi government have said they want -- a trial for Saddam and the departure of U.S. forces," he said. "We don't think this is going to be a huge number -- it's not going to be a million-man-march -- but we are taking precautions as we have done over recent months." U.S. forces were not in evidence on the streets, but Kadhim said they could be called in to support if needed. --SPA 1125 Local Time 0825 GMT www.spa.gov.sa/253164
