CAIRO- A mass trial of members of the outlawed Muslim Brotherhood began in Egypt on Saturday, but proceedings were abruptly cut short by the judge who said defence lawyers were being disruptive and "discussing politics", a judicial source told Reuters.
Judge Saeed Youssef Mohamed would announce his ruling on Monday and requested the lawyers of the 545 defendants to submit their written defense within 24 hours, the source said, declining to be identified.
The charges against the group, on trial in the province of Southern Minya, include storming a police station, attacking persons and damaging public and private property.
Only 123 of the defendants were present, the rest being either released, out on bail or on the run. Most were arrested during clashes which erupted in Minya after the forced dispersal of two Muslim Brotherhood protest camps in Cairo on August 14.
Tarek Fouda, head of the lawyer's syndicate in Minya said that the presiding judge had "veered away from all legal norms and that he breached the rights of the defense".
Fouda said he would submit a report on what had occurred at Saturday's hearing to Egypt's Justice Minister.
Hundreds died when security forces cleared the Cairo camps, where protesters had been calling for the reinstatement of former President Mohamed Morsi, ousted by the army in July. The events sparked violent protests all over Egypt.
Shortly after the army takeover, the authorities labelled the Muslim Brotherhood a "terrorist" organization and thousands of its members have since been arrested.
