Armed supporters of ousted Islamist president Mohamed Morsi seized two soldiers in Cairo after dozens were killed on Monday in clashes outside an elite military headquarters, an army official said. Both of the Egyptian soldiers, who were identified as Samir Abdallah Ali and Azzam Hazem Ali, were put in a vehicle and forced to make pro-Morsi and anti-army statements on a loudspeaker, the official said, cited by state news agency MENA.
