In the capital Cairo, security forces pumped volleys of tear gas at thousands of pro-democracy protesters clashing with riot police on streets several blocks from Tahrir Square and in front of the nearby parliament building.
Tens of thousands of activists massed in Tahrir itself, denouncing Morsi and chanting "Leave, leave" and "Morsi is Mubarak ... Revolution everywhere." Many of them represented Egypt's upper-class, liberal elite, which have largely stayed out of protests in past months but were prominent in the streets during the anti-Mubarak uprising that began Jan. 25, 2011.
"We are in a state of revolution. He is crazy of he thinks he can go back to one-man rule," one protester, Sara Khalili, said of Morsi.
"If the Brotherhood's slogan is 'Islam is the solution' ours is 'submission is not the solution'," said Khalili, a mass communications professor at the American University in Cairo. "God does not call for submission to another man's will."
Frustration had been growing for months with Morsi, Egypt's first freely elected president, who came to office in June. Critics say the Muslim Brotherhood, from which he hails, has been moving to monopolize power and that he has done little to tackle mounting economic problems and continuing insecurity, much less carry out deeper reforms.
