Egyptian security forces' vehicles reach Egypt's landmark Tahrir square after dispersing Cairo University's students backing ousted Islamist president Mohamed Morsi demonstrating against July's military "coup" on December 1, 2013 in Cairo, Egypt. Protesters were chanting "Down with the military regime!", "People want the fall of the regime!" and "Rabaa Rabaa", an AFP reporter said, as demonstrators flashed a four-finger sign that has become associated with a government crackdown on pro-Morsi supporters in Cairo's Rabaa al-Adawiya square on August 14.
