At least three people have been killed in the Egyptian capital, Cairo, as supporters and opponents of President Mohamed Morsi clashed near the presidential palace in Cairo, medics and police say, Aljazeera reported.
After a brief calm on Wednesday night, fighting extended into the early morning with fires burning in the streets where the opposing sides threw stones and petrol bombs at each other.
"No to dictatorship," Morsi's opponents chanted, while their rivals chanted: "Defending Morsi is defending Islam."
A small group of opposition activists have been camped outside the palace since Tuesday night, when tens of thousands rallied against a controversial decree which gives Morsi near-absolute power.
Supporters of the president marched to the palace on Wednesday and tore down the opposition's tents. Witnesses said they threw stones and used clubs to attack demonstrators. Opposition protesters were driven away from the palace and fled down side streets.
Thirty-two people were arrested, according to a statement from the interior ministry.
Protests spread to other cities, and offices of Morsi's Muslim Brotherhood in Ismailia and Suez were torched.
Both sides blamed the other for starting the clashes: Opposition leaders said Morsi was responsible for the bloodshed, while senior Brotherhood officials accused the opposition of "inciting violence".
