Interim president Adly Mansour "has tasked the armed forces, in cooperation with the police, to take all necessary measures to maintain security and order and to protect public and private property and the lives of citizens.
Security forces on Wednesday stormed two huge Cairo protest camps occupied for weeks by supporters of Egypt's ousted president Mohamed Morsi, leaving at least 124 people dead in a crackdown that turned into a bloodbath.
