Hundreds of Egyptians flocked to Tahrir Square in central Cairo on Friday to participate in a demonstration, calling on the authorities to grant their demands.

After the midnoon prayer, hundreds of people gathered at different districts of the capital, and then headed to Tahrir Square, causing traffic paralysation in the downtown area.

The demonstrators called on the head of the Supreme Council of the Armed Forces (SCAF) Hussein Tantawi to hand over power to civilians, with some of them demanding that former President Hosni Mubarak be executed.

"The protestors demanded that the ruling military council shift power to civilians," a witness named Sharif Sabry told Xinhua.

The protesters also called for stopping military trials against civilians and forming a 50-member advisory council chaired by political activist Ahmed Harara, a physician who were blinded in the unrest in January, 2011.

They announced that they would stage an open-ended sit-in and stage a one-million-man protest next Wednesday in front of the medical center where Mubarak was receiving treatment, the Egyptian newspaper al-Ahram's website reported.
