The trial of ousted Egyptian President Hosni Mubarak, charged with the killing of protesters and abuse of power, resumed on Wednesday following a delay of almost two months while lawyers demanded a new judge.
Mubarak, who is being held under arrest in a hospital where doctors say he has a heart condition, was wheeled into the court on a hospital trolley covering his eyes with his arm and surrounded by police.
Previous sessions were marred by clashes outside the Cairo court building between Mubarak supporters and Egyptians demanding the death penalty for their former leader, but there were no scuffles as Mubarak arrived on Wednesday.
Around 850 people were killed in the 18-day uprising that overthrew Mubarak in February.
The trial has gripped the Arab world, ruled mostly by autocrats who seemed unassailable until this year when Mubarak and the leaders of Tunisia and Libya were toppled in popular revolts.
Lawyers representing families of those killed had filed a suit calling for presiding judge Ahmed Refaat and the two other judges to be replaced. The request was rejected.
They had complained that the judges had failed to give them adequate time to question Field Marshal Mohamed Hussein Tantawi, who heads the army council now ruling Egypt, during his court appearance.
Former Interior Minister Habib al-Adli and six senior police officers are also standing trial. Businessman Hussein Salem, a close associate of Mubarak, is being tried in absentia.
The judge was expected on Wednesday to take requests from lawyers and set dates for more testimony.
