The judges presiding in an ongoing trial of Muslim Brotherhood spiritual leader Mohamed Badie and co-defendants on charges of incitement of murder have withdrawn from the case.
The three judges from the South Cairo Criminal Court cited a conflict of interest as their reason for stepping down, without giving further details.
Supreme Guide Mohamed Badie and his deputies Khairat El-Shater and Rashad Bayoumi are accused of inciting the murder of protesters at the Brotherhood guidance office headquarters in Cairo during clashes which took place on 30 June.
Nine protesters were killed and other 91 protesters were injured when fights broke out after anti-Brotherhood protesters stormed the building.
The South Cairo prosecution has referred six defendants to the criminal court for trial on the charges. The defendents include Mostafa Abdel-Azim, Mohamed Abdel-Azim and Atef Abdel-Galil.
Badie and El-Shater, along with former president Mohamed Morsi, are facing trials in a number of different cases.
Morsi is due to appear in court alongside 14 others on 4 November on charges of inciting murder and torture during deadly clashes between his supporters and opponents outside the Presidential Palace in December 2012.
The deposed president has refused to recognise the court, declining to delegate lawyers to defend him over murder allegations.
