Military Crackdown on Muslim Brotherhood

CNN is following the latest in Egypt where tensions simmered overnight.

On Wednesday, the Egyptian military removed President Mohamed Morsy from power, then installed the country’s chief judge Adly Mansour as interim president the following day.

The military has since been cracking down on supporters of Morsy. Both the deposed leader and several top leaders of the Muslim Brotherhood are now in custody and facing charges.

In return, the defiant Muslim Brotherhood is calling on its supporters to protest today, calling it “Friday of Rejection.”

CNN's Reza Sayah is in Cairo with more from the ground.

“More than 100 injured overnight as supporters and opponents of Mohamed Morsy and his Muslim Brotherhood movement clashed in three districts,” Sayah reports, “including the ousted president's hometown.”

With pro-Morsy demonstrations already underway in some areas now, “all of Egypt bracing is itself for what today could bring,” Sayah says.
