A member of the Muslim Brotherhood and supporter of deposed Egyptian President Mohamed Mursi attends a protest at the Rabaa Adawiya square where they are camping, in Cairo July 18, 2013. Brotherhood supporters will take to the streets on Friday in their campaign to reverse the military overthrow of Egypt’s first freely-elected president, but the movement also gave a first sign of willingness to negotiate with its opponents.
