The trial of former Egyptian president Hosni Mubarak resumed Monday with a court in Cairo set to hear testimony from a top Egyptian police official and several officers.

Mr. Mubarak was in attendance after arriving on a stretcher. Outside the court, security forces clashed with protesters, including some who threw stones at police.

The proceedings are not being televised, unlike two previous sessions that showed Mr. Mubarak lying on a hospital bed inside the courtroom's large metal cage with his two sons at his side. The judge presiding over the case ordered an end to the live broadcasts last month.

Mr. Mubarak has pleaded not guilty to charges that he ordered the killing of 850 protesters during the uprising that drove him from power earlier this year. He is also facing charges of corruption and abuse of power.

The former leader's sons, Alaa and Gamal, have denied separate corruption charges against them.

Mr. Mubarak is being tried along with former interior minister Habib al-Adly and six deputies, who are accused of giving orders that led to the killing of protesters.

Mr. Mubarak is the first Arab leader to face trial in person since the so-called “Arab Spring” of popular revolts swept across much of North Africa and the Middle East this year.
