Members of the Muslim Brotherhood and supporters of deposed Egyptian President Mohamed Mursi wave Egyptian flags, signs and masks of him as they gather at the Rabaa Adawiya square, where they are camping, in Cairo on July 12. Tens of thousands of Egyptians packed into squares and marched along streets in Cairo on Friday to protest against the military overthrow of Islamist President Mursi, and the US called for the first time for him to be freed.
