Muslim Brotherhood spokesperson Mahmoud Ghozlan has said its members are not in Tahrir Square and are therefore not responsible for the ongoing clashes.

"Members of the Muslim Brotherhood will not go to Tahrir Square until after afternoon prayers," Ghozlan said.

"Our members haven’t attacked anyone, the people fighting are supporters of the president," he added.

He went on to condemn allegations made by rival groups that Brotherhood members have been involved in the fighting.

"[Our members] are often assaulted but they never respond," he claimed.

The group was not responsible for the destruction of a stage in the square which took place early Friday afternoon, he added.

Tahrir Square has witnessed a series of ongoing clashes between supporters and opponents of the president, leaving a number of protesters injured.

Meanwhile, acting vice-chairman of the Freedom and Justice Party – the political wing of the Muslim Brotherhood – Essam El-Erian urged members of the group to meet at the high court building in downtown at 4pm.
