Thousands of Egyptians have packed Cairo's Tahrir Square for what they are calling a "Correcting the Path" protest.
The demonstrators are rallying Friday to voice their displeasure about what they say is the slow pace of governmental reform since former president Hosni Mubarak stepped down in February.
Protesters are trying to put pressure on the Supreme Council of the Armed Forces to provide a concrete timeline for the return to civilian rule in Egypt. They also want to end the practice of military trials for civilians.
Tahrir Square was the center of Egypt's "January 25 Revolution" which led to Mubarak's departure. It has largely been quiet since July, when security forces dispersed a sit-in by protesters.
Mubarak was in court again Thursday, facing charges that he ordered the killing of 850 protesters during the uprising that led to his February resignation. He is being tried along with former interior minister Habib al-Adly and six other deputies.
