The trial of ousted president Mohamed Morsi has been adjourned until 19 April in order to hear from new eyewitnesses.

Morsi, his presidential aides and other senior Muslim Brotherhood leaders are accused of inciting the murder and torture of opposition protesters outside the presidential palace in December 2012.

At least ten people were killed in the protests, triggered by a presidential decree that expanded Morsi's powers and put his decisions beyond judicial review.

Morsi, who was removed from power by the army in July 2013 amid nationwide protests against his year-long rule, also faces a number of other charges in separate trials, including espionage and breaking out of prison in the January 2011 uprising.

His jail break trial will resume on Tuesday and his espionage trial on Wednesday.
