Cairo Criminal Court will hear Sunday testimony of former Chief of Staff Sami Anan in the retrial of ousted president Hosni Mubarak, his two sons, Gamal and Alaa, his former interior minister Habib El-Adly, and six former security aides.

A media ban imposed on the retrail sessions in September, citing reasons of national security, will continue until Monday. Former head of the military police Hamdi Badeen is also scheduled to testify.

Former president Mubarak arrived Sunday morning at a courtroom on the outskirts of Cairo for his retrial over charges of complicity in the killing of demonstrators in the 2011 uprising that toppled him.

Mubarak, 85, was released from jail but is kept under house arrest in a military hospital in Maadi, a suburb of Cairo.

Former leader of the Supreme Council of the Armed Forces (SCAF), retired Field Marshal Hussein Tantawi, gave his testimony Saturday.

Several officials have been summoned to give testimonies, including ex-spy chief Mourad Mowafi, ex-military commander for the Cairo area, Hassan El-Roueini, Mubarak era premier Ahmed Nazif and former oil minister Sherif Ismail.

Mubarak and El-Adly were sentenced to life imprisonment in their original trial that concluded in 2012. That sentence was overturned on appeal in January because of "procedural failings."

Mubarak also faces charges of squandering public funds by selling natural gas to Israel at below market prices.

Mubarak's two sons, Alaa and Gamal, are also being retried on separate charges of financial corruption.
