The Way of the Revolution Front, an anti-military, anti-Muslim Brotherhood coalition group that participated in Saturday's demonstrations on the third anniversary of the 2011 January revolution, has urged its members to end their protests following clashes with security forces.

Police fired teargas and birdshot to disperse a protest by the group in the Giza district of Mohandiseen earlier on Friday. Members later regrouped in downtown Cairo before being attacked again by police.

"The font is urging all of its members and those who answered its call to commemorate the revolution anniversary to completely withdraw [from protests]," the group said in a Facebook statement.

"The excessive force that police forces are using against whoever tried to express their opinion is a major crime  ... while at the same time they were protecting their supporters in Tahrir Square.”

Thousands of supporters of the transitional authorities, and particularly of armed forces chief Abdel-Fattah El-Sisi, have gathered in Tahrir Square in central Cairo on Friday afternoon. Police have guarded the demonstration, searching participants entering the area.

"Saving the lives of those who are still adhering to the revolution’s values is a key revolutionary task. Our battles against the regime shall continue," read the statement.

The Way of The Revolution Front was launched last September, aiming to provide an alternative to the ongoing polarisation between the military and Muslim Brotherhood.
