Thousands of gathered in several cities across Egypt on Friday to press the country's military rulers to deliver on its promise of reforms and speed up the trials of former officials.
Many began to join those camping out in Cairo's Tahrir square, while thousands more gathered in the coastal city of Alexandria and the restive city of Suez, east of Cairo, DPA reported.
The Revolution's Youth Coalition, an opposition group, have called on Egyptians to join in the demonstration dubbed the "Friday of the Last Ultimatum."
Protesters are demanding swift public trials for former president Hosny Mubarak and officials from his regime.
Mubarak was forced to step down in February due to a popular revolt that prompted government crackdown in which 850 people were killed and more than 6,000 injured.
He has denied responsibility for the death of protesters, according to transcripts from his interrogation, which were leaked to the media Thursday.
Mubarak and his sons, Alaa and Gamal, are to face trial on August 3 on charges of involvement in killing of protesters as well as corruption and profiteering.
The former president is currently in custody in a hospital in the Red Sea resort of Sharm el-Sheikh. One of the protesters' demands is that he must be transferred to Cairo's Tora prison, where all ex-officials await trial.
Although it had been credited with supporting the revolution initially, the Supreme Council of the Armed Forces has come under fire from political activisits accusing it of protecting Mubarak.
