A move by Egypt's military rulers to bring forward the transfer of power to a civilian government has failed to win over thousands of street protesters in Cairo.
In major concessions following a crisis summit, the military council said the handover would be in July next year. It also consulted with political parties on forming a new cabinet.
But the Tahrir Square demonstrators rejected the move, threatening a "second revolution."
"We are not leaving, he leaves," chanted the protesters, demanding that military ruler Field Marshal Hussein Tantawi and his council of generals immediately give up power to a civilian transitional authority.
"The people want to bring down the field marshal," they shouted in scenes starkly reminiscent of the uprising that ousted Hosni Mubarak nine months ago.
Aboul-Ela Madi and Mohammed Selim el-Awa, two politicians who attended a five-hour crisis meeting with the military rulers, said the generals accepted the resignation of Prime Minister Essam Sharaf's government and will form a "national salvation" cabinet to replace it. Previously, the military rulers had floated late next year or early 2013 as the timetable for transferring power.
The military's concession came less than a week before the first parliamentary election since the removal nine months ago of Mubarak. The elections are staggered over three months.
"Our demands are clear. We want the military council to step down and hand over authority to a national salvation government with full authority," said Khaled El-Sayed, a member of the Youth Revolution Coalition and a candidate in the upcoming parliamentary election. The commander of the Military Police and the Interior Minister, who is in charge of the police, must be tried for the "horrific crimes" of the past few days, he added.
"This is the maximum we can reach. The (Tahrir) square is something and the politics is something else," Mr Madi said. He and Mr Al-Awa were among 12 political party representatives and presidential hopefuls who attended the meeting with the military council. Not all parties were represented.
They also said the military agreed to release all protesters detained since Saturday and to put on trial police and army officers responsible for protesters' deaths. Nearly 30 protesters have been killed since Saturday.
