Security forces applied water cannons at protesters then fired teargas and birdshot, according to an Ahram Online reporter at the scene.

The statement added that the protests were peaceful until 6PM, where elements of the outlawed Muslim Brotherhood joined the protests in Abdel-Moneim Reyad Square, a short distance from the closed Tahrir Square.

The Brotherhood members, the statement read, chanted anti-army and police slogans and threw rocks at the security forces.

The statement adds that protesters were warned to leave but they insisted on staying prompting the police to disperse them.
