Islamists planning protests when deposed Egyptian president Mohamed Morsi's trial starts next week said Friday they will rally outside the heavily guarded court, raising the prospect of clashes with police. "The mass rally on Monday... should be outside the (Police Officers' Academy) building in Tora," the Anti-Coup Coalition, which is led by Morsi's Muslim Brotherhood, said in a statement. The Coalition, which demands Morsi's reinstatement, also called for rallies across Egypt starting on Friday. Interior ministry officials say 20,000 policemen will be deployed on Monday to guard the south Cairo academy hosting the trial and to secure Morsi's transport to the makeshift court room.
