Egypt on high alert as Mohammed Morsi trial looms
Egypt's ousted former President Mohammed Morsi is due to stand trial on Monday, along with 14 other senior Muslim Brotherhood figures, the BBC reported.
They are charged with inciting the killing of protesters during clashes outside the presidential palace last December.
Security services are on high alert after supporters of the former president called for major protests.
Mr Morsi was ousted by the military in July after protests against his rule.
Although he won the presidency in a democratic election, during his 13 months in power Mr Morsi fell out with key institutions.
After he was ousted, a sit-in protest in Cairo by Mr Morsi's supporters was violently broken up by the military, leading to the deaths of hundreds of people.
The interim government has also cracked down on the Muslim Brotherhood, from which Mr Morsi hails, banning the Islamist organisation and arresting dozens of senior figures.
His supporters say he was removed in a coup and is now facing a politicised trial. Human rights groups accuse the security services of acting without accountability.
On Saturday, Egyptian newspaper al-Watan published what it said were the first images of Mr Morsi in detention.
The images, which have not been independently verified and are undated, show Mr Morsi dressed in a tracksuit and sitting in an armchair, appearing animated and comfortable.
He has been held at a secret location since he was ousted by the military, who had given the then-president a 48-hour ultimatum to end mass protests against his rule.
It is thought Mr Morsi's trial will be held at the Police Academy in Cairo and is expected to start between 07:00 and 08:00 GMT.
The trial of his predecessor, Hosni Mubarak, is being held at the same location - meaning there two former Egyptian presidents being tried concurrently.
