Presidential candidate Mohamed Morsy of the Muslim Brotherhood waves to a crowd outside a mosque after attending Friday Prayers in Cairo, June 15, 2012. Activists called for a protest on Friday and Islamists warned that the gains of the revolt that toppled Hosni Mubarak could be wiped out after Egypt's supreme court dissolved parliament and ruled to keep his last premier in this weekend's presidential race.
