"The country has been liberated after decades of repression," he said adding that he expects a "beautiful" transition of power.
Outside Mubarak's Oruba Palace in northern Cairo, women on balconies ululated with the joyous tongue-trilling used to mark weddings and births.
Mohammed el-Masry, weeping with joy, said he had spent the past two weeks in Tahrir before marching to the palace Friday. He was now headed back to the square to join his ecstatic colleagues. "We made it," he gasped.
The question now turned to how the military, long Egypt's most powerful institution and now its official ruler, will handle the transition in power. Earlier in the day, the Armed Forces Supreme Council — the military's top body — vowed to guide the country to greater democracy. State TV said a new statement by the military would be issued Friday evening.
Abdel-Rahman Samir, one of the youth organizers of the protests, said the protest movement would now open negotiations with the military over democratic reform but vowed protests would continue to ensure change is carried out.
"We still don't have any guarantees yet — if we end the whole situation now the it's like we haven't done anything," he said. "So we need to keep sitting in Tahrir until we get all our demands."
But, he added, "I feel fantastic. .... I feel like we have worked so hard, we planted a seed for a year and a half and now we are now finally sowing the fruits."
