Media reports say that nearly a dozen men, armed with knives hurled brick and petrol bombs at the headquarters of Egypt's state security. It was the atrocities and abuses by the same force that led people to revolt and consequently topple Mubarak's regime.
When they were confronted with Egyptian soldiers who fired into the air several times to disperse the protesters, they begin to run away. As they fled, they encountered men whom they called as thugs.
Reuters has quoted Mohammed Fahmy, a citizen of Egypt as saying, "The army started firing in the air to disperse us..We tried to run away but we were met by 200 thugs in plain clothes carrying sharp weapons on the other side."
He was reported him as saying that 15 protesters were injured in the conflicts.
The Egyptian military council that seiged power from Mubarak, has replaced the prime-minister appointed by the former president until constitutional amendments are done and democracy restored in the country.
