Supporters of Egypt's ousted Islamist president Mohamed Morsi hold posters of the four finger symbol, known as "Rabaa", which means four in Arabic, to remember those killed in the crackdown on the Rabaa al-Adawiya protest camp in Cairo earlier in the year, as they take part in a demonstration against the military on September 20, 2013 along the seafront in the northern coastal city of Alexandria. Egypt's army-backed authorities arrested the spokesman of the Muslim Brotherhood on September 17 and froze the assets of other Islamists, in a new blow to deposed president Mohamed Morsi's supporters.
