In an official statement published by Al-Ahram Arabic news website, the army said an “armed terrorist group” attempted to break into the Republican Guard headquarters in the early hours of Monday and “attacked security forces.”
One officer died and 40 soldiers were injured, including seven in critical condition, the statement said.
The Muslim Brotherhood said the army used live ammunition against the protesters.
Brotherhood spokesperson Gehad El-Haddad said via Twitter that 37 people were killed.
The army said it had arrested at least 200 people who had “large quantities of firearms, ammunition and Molotov cocktails.”
It also said that it had reopened Salah Salem Road which had been blocked by pro-Morsi protesters.
President Morsi was deposed by Egypt’s Armed Forces on Wednesday following nationwide protests calling for his ouster. Judge Adly Mansour, the head of the High Constitutional Court, was sworn in as the country’s interim president on Thursday.
Morsi’s removal sparked anger among his supporters, mainly Islamists, spearheaded by the Muslim Brotherhood.
The National Alliance for Supporting Legitimacy, a pro-Morsi group formed to back his right to complete his term of office, continues its sit-in at Rabaa Al-Adawiya Mosque in Cairo’s Nasr City district.
Other pro-Morsi groups have been protesting elsewhere, most notable at Nahdet Misr Square in Giza.
El-Haddad called on “all patriotic brave Egyptians to join [pro-Morsi protesters] at Rabaa Al-Adawiya and [Nahdet Misr] to defend the country from conspiratorial traitors of the military coup.” – AhramOnline.
