Egypt's military warned on Thursday that it was prepared to use force against what it called "violence and black terrorism" as protests over the ouster of President Mohammed Morsi continued, NBC News reported. A statement headlined "the last chance" said the commander of the armed forces was going to change strategy in order to maintain national security and stability. It gave protestors 48 hours to "retreat" and "get in line with the rest of the nation." Prime Minister Hazem el-Beblawy said there were escalating attacks on government institutions by well-armed protestors. Close to 200 people have died since Morsi's ouster on July 3.
