Supporters of Egyptian ousted president Mohamed Morsi and of the Muslim brotherhood movement hold posters depicting Morsi and the Rabaa sign during a rally outside the al-Quba presidential palace in Cairo on October 11, 2013. An Islamist alliance urged its supporters to stay away from Cairo's Tahrir Square during protests to avoid more bloodshed after a week in which nearly 80 Egyptians were killed. The "Rabaa", which means four in Arabic, refers to those killed in the crackdown on the Rabaa al-Adawiya protest camp in Cairo earlier in the year.
