Police forces arrested 34 protesters who took to the streets on Wednesday to commemorate the third anniversary of Mohamed Mahmoud clashes, a security source said.
The security source, who preferred to remain anonymous, added to Aswat Masriya that those arrested were transferred to the Cairo Security Headquarters.
Security forces cordoned Talaat Harb Square with armoured vehicles, eye-witnesses said. Police fired warning shots and dispersed protests around the square, a security source, who preferred to remain anonymous, told Aswat Masriya.
Protesters arrested belong to youth political movements including the April 6 Youth Movement and the Revolutionary Socialists, the source added.
The Mohamed Mahmoud clashes erupted on November 19, 2011, stretching for five days. The clashes between security forces and protesters opposing the then-ruling Supreme Council of the Armed Forces (SCAF) were the deadliest since the January 2011 uprising which toppled President Hosni Mubarak. The clashes left almost 50 killed.
