CAIRO — Thousands of people have filled Cairo's Tahrir Square to call for Egypt's military rulers to harshly punish members of ex-President Hosni Mubarak's former administration.

The demonstration, dubbed "Friday for the Rescue of the Revolution," was organized by the Youth Revolution Coalition, a group founded by the young activists who started Jan. 25 protests that led to Mubarak's ouster.

The protesters are calling for trials of remaining members of Mubarak's regime, namely Fathi Serour, the former parliament speaker; Zakariya Azmi, head of the presidential palace; and Safwat al-Sherif, the former secretary general of the ruling party.

They also call for swift measures to bring back money and assets, taken over by Mubarak and his men from abroad.
