Egypt opposition in clashes on revolution anniversary

Egyptian opposition supporters are gathering in central Cairo to mark two years since the start of the uprising that swept Hosni Mubarak from power.

Police clashed with opponents of President Mohammed Morsi who are now converging on Tahrir Square.

There are clashes in Alexandria and Suez. In Ismailia protesters set fire to the Muslim Brotherhood's party HQ.

Critics accuse Mr Morsi of betraying the revolution. He denies this and has appealed for calm.

An appeals court recently overturned Mr Mubarak's life sentence over the deaths of protesters and ordered a retrial.

The 84-year-old former leader remains in detention at a military hospital.
