More than 650 questioned on Cairo clash which left 51 dead

Egyptian authorities are questioning 650 people to establish what started the deadly clashes outside Republican Guards barracks in Cairo Monday, in which more than 51 people were killed. The Muslim Brotherhood accuses the army of shooting live bullets and tear gas at a peaceful sit-in of their supporters outside the barracks where deposed President Morsi is held. Some witnesses confirm the army’s contention that Brotherhood supporters attacked the military facility, attesting to firing on both sides.
