Egypt's Muslim Brotherhood called for mass protests Friday against the military-backed ouster of President Mohamed Morsi.
The Brotherhood is part of an alliance of Islamist parties calling for peaceful protests to follow afternoon prayers across the country.
Until now, the atmosphere on the streets has been largely celebratory since Mr. Morsi was forced out by the military following large opposition protests.
He was replaced by Adly Mansour, a top judge who was sworn in Thursday as interim president -- a move that was quickly rejected by the Brotherhood.
Islam Abdel-Rahman, who is on the the foreign affairs committee of the Muslim Brotherhood's Freedom and Justice Party, tells VOA that his group will not take part in any military-led political process.
