Thousands of Egyptians flocked to central Cairo's Tahrir Square in what they called "Revolution First" Friday, calling for the ruling military to achieve all demands of the Jan. 25 Revolution.

They also called for purifying and restructuring the police institutions, and speeding up trials of all former regime officials and police officers involved in killing protesters and causing chaos.

More than 20 pro-democracy political parties and groups participated in the protests, asserted the unity between the people and the army, and reaffirmed their trust in the Supreme Council of the Armed Forces that is running the country in the transition period.

Also among the main demands are to regain the stolen wealth by the figures of the former regime and cleanse the current government from those who were affiliated to the Mubarak era.

Kamal Abou El-Yazid, a 36-year-old member of Youth Coalition Union, said "we didn't feel any change, a court decision to dismantle all the municipal councils must be implemented urgently. "

He added, "those councils were ruled by the former ruling National Democratic Party members to achieve their personal interests, instead of the people's interests."

Protesters have set up dozens of tents everywhere in the square, the epic center for toppling former President Hosni Mubarak, and are determined not to leave until their demands are met.

Wrangles erupted upon speech stages among the supporters of presidential hopeful Mohamed ElBaradie and youth groups from one side and Muslim Brotherhood members from the other side.

Due to the recent clashes, some young protestors wore T-shirts reading "public security" to protect protestors. They check the IDs of all participants at entrances of the square and prevent the infiltration of any thugs.

Interior Minister Mansour al-Essawi said the police forces will not be present at the square and they will only intervene if they are asked to.
