The Muslim Brotherhood and supporters of ousted Egyptian President Mohamed Mursi fire flares and stones at anti-Mursi protesters and riot police during clashes along a road at The Ramsis square which leads to Tahrir Square during a celebration commemorating Egypt's 1973 war with Israel in Cairo October 6, 2013. At least 28 people were killed and more than 90 wounded in clashes during protests in Egypt on Sunday, security sources and state media said, as the crisis since the army seized power three months ago showed no sign of abating. | Foto: REUTERS/Amr Abdallah Dalsh
