Mubarak is in a military hospital. In January a Cairo court granted him the retrial after he was jailed for life over the killing of protesters in early 2011 by security forces trying to quell the uprising against him.
"Samir Abu el Maati, the head of the Appeals Court has set April 13 as the retrial date for former President Hosni Mubarak, his two sons Gamal and Alaa and his interior minister Habib el-Adly and six of his top aides ... on charges of killing of protesters during the January 25th revolution," MENA state news agency said.
Mubarak, 84, was ousted in February 2011 after 30 years in power and was the first Arab ruler to be brought to court by his own people.
