Thousands of supporters and opponents of Egyptian President Hosni Mubarak battled in Cairo's main square all day Wednesday, raining stones, bottles and firebombs on each other in scenes of uncontrolled violence as soldiers stood by without intervening. Government backers galloped in on horses and camels, only to be dragged to the ground and beaten bloody. (AP Photo/Lefteris Pitarakis)
