It said the former leader would stand trial along with 14 other suspects in his Muslim Brotherhood movement on charges of "incitement to murder and violence" in December 2012 when deadly clashes broke out between his supporters and opponents outside the presidential palace.

Already accused of charges related to his 2011 escape from prison, Morsi has been held at a secret location since his ouster by the army on July 3.

The co-defendants in the trial include senior Brotherhood figures Mohamed al-Beltagi and leaders such as Essam el-Erian, deputy head of the Freedom and Justice Party, the Brotherhood's political wing.

Last December, thousands of demonstrators gathered in front of the presidential palace in Cairo to protest against a presidential decree that expanded Morsi's powers and an Islamist-drafted constitution.

Egypt has pressed a fierce campaign against the Brotherhood since the former president's ouster and effectively decapitated the Islamist group by arresting its supreme guide Mohamed Badie in late August.

Authorities have also arrested more than 2,000 Brotherhood figures since Morsi's ouster.

Brotherhood defendants, including Badie, were due to appear in court on August 25 but kept away for what authorities said were security reasons. A new hearing is to take place on October 29.

Badie and his deputies Khairat al-Shater and Rashad al-Bayoumi face charges related to the deaths of protesters who stormed the Brotherhood's Cairo headquarters on June 30.
