CAIRO: Protestors rallied and returned to Cairo's Tahrir Square, calling on the Field Marshall Hussein Tantawi to step down, after military and security forces violently evicted them from the square early Sunday evening. Security forces broke up the crowd using tear gas, burned tents of those protesting, and fired on protestors. Ambulances shuttled the injured out of the square. The Arabic edition of Youm7 reported that security forces arrested dozens of protesters while others fled to side streets around Tahrir Square.
