Hundreds of war protesters from across the US gathered in Washington on Saturday to mark the sixth anniversary of the invasion of Iraq. Organizers from the ANSWER Coalition said more than 1,000 groups sponsored the protest to call for an end to the Iraq war. Holding signs that read "We need jobs and schools, not war" and "Stop the war!" they rallied around noon across the street from the Lincoln Memorial and were beginning to march across the Memorial Bridge to the Pentagon. Protesters demanded that US President Barack Obama immediately withdraw all US troops from Iraq, saying thousands of Iraqis have died and thousands of American troops have been killed or wounded. Protesters lined up about 100 cardboard coffins on the ground draped with flags, including the American flag, representing countries where the US has taken military action.
