Political tensions have gripped Egypt and stymied its economy since the army ousted Morsi, installed an interim government and drew up a political road map that it promised would bring fair elections.
On Saturday an estimated 1,000 anti-government protesters tried to reach Rabaa al-Adawiya Mosque in northeastern Cairo, where security forces crushed a protest camps in August. All but about 50 protesters were turned back by police, who fired tear gas, security sources said.
Interior Minister Mohamed Ibrahim said security forces would not tolerate attempts to block roads or "spread chaos," Egypt's state news agency reported. The Interior Ministry said security had been stepped up on highways, in all cities and at important installations.
"The ministry will deal with the utmost firmness and decisiveness with any of those practices and confront any lawlessness," he was quoted as saying.
Prime Minister Hazem el-Beblawi said in a statement to the nation that "evil elements" still posed a danger but had lost much of their power — an apparent reference to the Muslim Brotherhood.
State security forces killed hundreds of people in a crackdown on the Islamist group, which successfully fielded political candidates in elections after Mubarak's fall but lost favor with the public during Morsi's rule. Many Egyptians accused him of trying to acquire sweeping powers and mismanaging the economy — allegations he denied.
