On the night of 3 July , General Abdel Fattah el-Sisi , head of the Egyptian Armed Forces , announced in a live televised address that Mohamed Morsi had been deposed and replaced by the head of the constitutional court Adly Mansour and that the constitution had been suspended . Morsi was immediately detained and kept under house arrest at the Republican Guard headquarters in Cairo while several other government officials and Islamist figures supporting Morsi were also arrested . The move marked a turning point for the country 's future and for the fate of the Muslim Brotherhood , as it was designated a terrorist group later that year in response to a bombing in Mansoura ( even though Ansar Bait al-Maqdis claimed responsibility ) and was subjected to an unprecedented crackdown amid an ongoing Islamist unrest . A crackdown by the military on the sit-in at Rabaa al-Adawiya Square led to the August 2013 Rabaa massacre , which Human Rights Watch described as ' one of the world 's largest killings of demonstrators in a single day in recent history ' and led to the deaths of at least 817 people in Rabaa itself and 904 people across the country by the end of 14 August . Ten members of the security forces were also killed
