CAIRO - The fourth session of the retrial of Egyptian ex-president Hosni Mubarak, his two sons, former interior minister and six of his aids over killing protesters in 2011 kicked off at Cairo Criminal Court on Saturday.

In a televised session, presiding judge Mahmoud Kamel said that he received the case four months ago and that the staff had studied numerous files on the case.

Kamel called the media as "the eye of justice," demanding media channels to broadcast a CD including all the names of the dead and the injured during the 2011 unrest.

On June 20, An Egyptian court decided to release Mubarak over investigations of illicit gains. Similarly, in mid-April, a court decided to temporarily release Mubarak over responsibility of killing protesters in the January 2011 upheaval that led to his downfall.

However, the ex-president will have to stay in custody over other charges, mainly the looting of public funds allocated for the maintenance of presidential palaces.
