Egypt's Muslim Brotherhood-led coalition has called for mass demonstrations across the country starting Friday until the trial of the country's ousted president begins.

The trial of toppled President Mohammed Morsi is set to begin Nov. 4. Morsi, ousted in a July 3 coup, faces charges of inciting murder and violence in connection to deadly clashes outside presidential palace in December.

Some fear the trial will mark a new cycle of turmoil in Egypt. Since the coup, Egypt witnessed one of its worst bloodbaths when security forces violently cleared protest camps in Cairo, leaving hundreds dead and sparked weeks of unrest.

Morsi has been detained in undisclosed military facility since the coup. He has spoken twice to his family by telephone.
