Cairo Criminal Court decided to postpone until next Sunday the trial of 17 senior members of the terrorist Muslim Brotherhood (MB) till the first day of November.
The defendants are accused of killing peaceful demonstrators who organized protests in front of the MB guidance office in Mokattam during the June 30 Revolution.
The postponement decision comes to hear the pleading of the defendants' lawyers.
The Mokattam clashes left at least nine people dead and 91 others injured.
