Egypt should investigate and discipline police and plainclothes security officials who beat demonstrators protesting the Iraq war and tortured some of those detained. In this 40-page report, Human Rights Watch documents excessive use of force by security forces to disperse demonstrators protesting the U.S.-led war against Iraq in March, violating their right to freedom of assembly. After arresting hundreds of protesters, police then beat and mistreated many detainees, some to the point of torture, and failed to provide medical care to persons seriously injured. Human Rights Watch calls on the government to dismiss charges against persons detained solely for attempting to exercise their right of free assembly.
