The Muslim Brotherhood’s main office in Cairo was set ablaze on Thursday, the group’s political party said, and another office used by the party was torched in a suburb south of the city, the state news agency reported.
The Freedom and Justice Party said on its Facebook page that the headquarters in the Mukattam district had been attacked in “a terrorist aggression” by thugs.
The state news agency said the office used by the FJP was set ablaze in the Cairo suburb of Maadi. Another office was broken into near the city center, it said.
“Two hundred thugs went to the headquarters. Security tried to prevent them, but some got through the back door, ransacked it and set it on fire. It is still burning now,” Brotherhood spokesman Mahmud Ghozlan said.
Reporters at the scene said there were fierce clashes between the protesters and police, who fired tear gas.
The attack followed an address by Egypt’s President Mohamed Mursi on Thursday night, in which he defied calls to curb his sweeping powers, infuriating thousands of protesters who have clashed bloodily with his supporters in recent days.
In an address broadcast live, Morsi vowed to push on with a Dec. 15 referendum on a controversial new constitution, saying “afterwards, there should be no obstacle and everyone must follow its will.”
