The trial of Egypt's ex-President Hosni Mubarak on charges of ordering the killing of protesters in this year's uprising has resumed in Cairo, with uproar inside and outside court.

Hundreds of riot police were deployed outside the police academy where the trial is taking place.

Hosni Mubarak, who is 83 and reported to be in a poor state of health, was again wheeled into a cage in court on a hospital bed.

Mr Mubarak's son Alaa, who is also on trial, tried to stop state television taking pictures of his father.

The judge struggled to retain order inside court, with dozens of lawyers jostling to be heard.

Hundreds of Mubarak supporters protested against what they called the "humiliation" of the former leader.

But opponents made it clear what they thought the verdict - and sentence - should be.

Clashes between the rivals caused a number of casualties.
