Egyptian security forces are on high alert for a court appearance in the capital Cairo by deposed President Mohammed Morsi.
Morsi and 14 other Muslim Brotherhood figures are accused of inciting the killing of protesters outside the presidential palace in December 2012.
Last Friday at least 11 people died in clashes between police and Muslim Brotherhood demonstrators across Egypt.
Morsi also faces other charges ranging from colluding with foreign militants in a terrorist plot to jail breaking.
