The 2013 Egyptian coup d'état took place on July 3, 2013. Egyptian army chief General Abdel Fattah al-Sisi led a coalition to remove Morsi from power and suspended the Egyptian constitution of 2012 after the military's ultimatum for the government to "resolve its differences" with protesters during widespread national protests. The military arrested Morsi and Muslim Brotherhood leaders, and declared Chief Justice of the Supreme Constitutional Court Adly Mansour as the interim president of Egypt. Ensuing protests in favour of Morsi were violently suppressed culminating with the dispersal and massacre of pro-Morsi sit-ins on August 14, 2013, amid ongoing unrest; journalists, and several hundred protestors were killed by police and military force.
