Muslim Brotherhood allies were there performing dawn prayer during a sit-in meant to demand his release, according to the AP. Morsi, who had been accused of strong-arming his party into power, was deposed by the military Wednesday. His successor, Adly Mansour, is charged with creating a temporary government.
