Egyptian prosecutors say they are presenting new evidence in the retrial of former President Hosni Mubarak.

Mubarak, all in white and wearing sunglasses, attended the hearing in the courtroom defendants' cage alongside his two sons and former interior minister, who was in charge of police at the time.

All pleaded not guilty to the various charges, which include allegations of involvement in the deaths of 900 protesters during Egypt's 2011 revolt as well as corruption.

Mubarak was airlifted to the Cairo court from a nearby prison.

State TV carried Saturday's session live from the courtroom.

Prosecutors told Judge Mahmoud Kamel el-Rachidi that they are presenting new evidence from a fact-finding committee's report.

The retrial comes after an appeals court overturned Mubarak's conviction for failing to prevent protester killings.
