CAIRO, Nov. 23 (UPI) -- Egyptian opposition supporters set fire to Muslim Brotherhood offices in several Egyptian cities on Friday -- the day after the president assumed more powers.

Muslim Brotherhood offices were seen on fire in the Suez Canal cities of Suez, Port Said, and Ismailia, Voice of America reported.

Meanwhile, thousands of Morsi's backers gathered outside of the presidential palace, the BBC reported.

Despite the protests Morsi has vowed to protect the rights of the opposition, saying, "There is a great future for this nation."

On Thursday, Morsi issued a decree stating that all decisions he has made since taking office are not subject to review or appeal.

Mohamed ElBaradei, Nobel Peace Prize laureate who heads the lawyers syndicate and is a key opposition figure, sent out the call for Egyptians to protest Friday, BBC reported.

The president "appointed himself Egypt's new pharaoh. A major blow to the revolution that could have dire consequences," ElBaradei wrote on Twitter.

Protesters have picked up on the moniker and are referring to Morsi as the "new pharaoh," Ahram Online reported.

The total number of protesters in Tahrir Square and throughout Egypt has not been reported, though Ahram Online said two tents -- one for the Constitution Party and the other for the Popular Current -- were set up in Tahrir.

Security forces and protesters clashed throughout Thursday night into Friday morning along Mohamed Mahmoud Street in Cairo, near Tahrir Square.

"We have had around 20 major injuries last night, all from tear gas," said paramedic Mohamed Hamdi.
