Dozens of protesters converged on the Ittihadiya presidential palace in Cairo on Tuesday evening, in celebration of the 61st anniversary of the 1952 revolution which overthrew Egypt's 150-year-old monarchy.

The revolution was led by the Free Officers Movement which included three men who would go on to become president - Mohamed Naguib, Gamal Abdel-Nasser and Anwar El-Sadat.

Protesters are reportedly gathering in front of the palace's Gate 4, chanting pro-military slogans.

A substantial number of security forces have been deployed to the area.

Hundreds are also celebrating the revolution's anniversary in Tahrir Square, holding pictures of Abdel-Nasser.
