Sporadic clashes broke out overnight between protesters demanding the ouster of Egypt's Islamist President Mohamed Morsi and security forces outside the presidential palace, witnesses said on Sunday.
There were no reports of casualties from the confrontations which follow violent clashes on Friday outside the presidential palace that left one person dead.
Late on Saturday several hundred mostly young protesters again gathered outside the compound and threw stones and petrol bombs at its walls, an AFP correspondent said.
One protester said they were there to pay homage to the young man killed on Friday, and they chanted "Leave!" and "The people want the regime to fall!" -- slogans used two years earlier against ousted dictator Hosni Mubarak.
Security forces deployed outside the palace grounds fired tear gas overnight when protesters tried to storm one of the gates, the witnesses said.
The head of the military's Republican Guards, tasked with protecting the presidency, said his troops would ignore "provocation" from protesters, the official MENA news agency reported.
On Sunday, calm prevailed in Cairo but the widening gap between the presidency and the opposition was evident.
Since the start of the new wave of violence in Egypt on January 24, the eve of the second anniversary of the uprising that ousted Mubarak, nearly 60 people have been killed in the country.
