The tense situation in Egypt grows even more fragile this morning.

Removed from power Wednesday night, deposed President Mohamed Morsy is now in military custody along with several top leaders of the Muslim Brotherhood.

While opponents of Morsy and the Brotherhood are celebrating the events of the past week, supporters are calling for mass protests.

Reza Sayah is live in Cairo with the latest.

“One day after the armed forces toppled him from power, Egypt's top prosecutor banned Morsy from leaving the country, then launched an investigation into accusations that the former president incited deadly violence,” Sayah reports.

“More than 30 Muslim Brotherhood leaders, also in custody and facing charges.”

Interim President Adly Mansour reached out to the president's supporters after being sworn in on Thursday, inviting the Muslim Brotherhood to help build the nation.

But many among the Brotherhood are not swayed.

“Instead they're planning a day of protests,” Sayah says, “calling it ‘Friday of Rejection.’” Those demonstrations are set to begin after Friday prayers.

“Some of the most hard-lined supporters of the Brotherhood, Mr. Morsy, have made provocative statements saying they’re prepared to die," Sayah says. "Others Brotherhood leaders are saying keep things peaceful.”
