Judges also combined the case against Mubarak with that of former Interior Minister Habib al-Adly, Refaat said.

Both men potentially face the death penalty if found guilty of ordering the killing of protesters in the revolution that toppled them earlier this year.

The trial will resume September 5, the judge said, giving officials more time to study evidence. Some prominent Mubarak opponents welcomed the decision not to televise the trial until the announcement of the verdict.

But many people expressed anger about the decision, including Wael Omar, a founding member of Radio Tahrir. Small crowds of Mubarak supporters clashed with opponents of the former Egyptian president Monday as he and his sons appeared at the court hearing.

About 840 people died and more than 6,000 were wounded in the 18 days of uprising that toppled Mubarak, bringing an end to his 30-year reign, according to Amnesty International.

In addition to accusations of ordering the killing of protesters, Mubarak faces corruption charges. His sons Alaa and Gamal also face corruption charges. All three of them have pleaded not guilty.
