Egyptians shout as they wave a giant flag during a demonstration at Tahrir Square, Cairo, April 1, 2011, to call for the military government to harshly punish members of ex-President Hosni Mubarak's former administration
Thousands of demonstrators filled Tahrir (Liberation) Square in Cairo Friday, calling on the Egyptian transitional military-run government to keep up political and social reforms.
The protest to "save the revolution" was organized by the Youth Revolution Coalition, a group of young activists who helped start the January 25 protests that led to the overthrow of President Hosni Mubarak.
Demonstrators are calling for the prosecution of several top members of Mubarak's government, and an end to military detainment of civilians.
Mubarak and his family remain under house arrest in Egypt. The military is denying rumors that he left for Saudi Arabia after his ouster to seek medical treatment.
The Supreme Council of the Armed Forces that has ruled Egypt since Mubarak's ouster announced this week that presidential elections will take place by November.
It also unveiled an interim constitution under which the Egyptian military has promised to rule until handing power to an elected president and parliament.
The military has promised that Egypt's emergency laws that were put in place when President Mubarak took office in 1981 will be lifted before September's parliamentary contest.
Earlier this month, millions of Egyptians voted in favor of constitutional amendments aimed at paving the way for free and fair elections for parliament and president. The amendments were proposed by a military-appointed panel of legal experts.
