At least two people have been killed and 18 others injured as thousands of Egyptians were calling for trial of ousted President Hosni Mubarak clashed with security forces in Cairo's' Liberation Square.

On Saturday, security forces faced off with Egyptian protesters, who converged onto the iconic square to ask for the immediate prosecution of Mubarak and his henchmen, media reported.

The protest turned violent as anti-riot police fired into the air.

The angry crowd on Saturday promised to remain relentless in the pursuit of their demands, including the social reforms and the prosecutions of former regime figures.

They also want the Egyptian army to hand over power to a civilian government as part of the promised reforms.

The protests come weeks after Mubarak handed over power to Egypt's Supreme Council of the Armed Forces, headed by Defense Minister Gen. Mohammed Tantawi.

Activists demand the release of political prisoners, the lifting of a 30-year-old state of emergency and the disbandment of the military court.
