The trial of former Egyptian president Hosni Mubarak has been postponed until next Wednesday after resuming for the first time in two months.
The 83-year-old, who faces charges of abuse of power and killing protesters, was stretchered out of the courtroom on a hospital trolley.
His sons, Gamal and Alaa, also face allegations of corruption and could face up to 15 years in jail if convicted.
Mubarak may be sentenced to death if he is found guilty of ordering security forces to kill those who demonstrated against his three decade rule in February.
More than 800 people died during the 18-day uprising.
Lawyers representing the victims’ families had asked for the presiding judge and his two others to be replaced.
That request was rejected earlier this month.
