Muslim Brotherhood Begins March in the Wake of Crackdown

Police have been authorized to use deadly force


Thousands of supporters of the ousted Egyptian President Mohammed Morsi have started fresh protests in the capital, Cairo, amid fears of further clashes.

Security forces are reported to have blocked off the focal point of their demonstrations, central Ramses Square.

The protests are taking place two days after Muslim Brotherhood camps were broken up, leaving at least 638 dead.

Protests are also being held outside Cairo. Four people were reportedly killed in clashes in Ismailia.
