Several hundreds of Egyptians protested in central Cairo on Monday against a court ruling that sent three leading secular pro-democracy campaigners to jail, witnesses said. Raising a banner reading "Freedom for all detainees", the protesters chanted against the military-backed government, calling army chief General Abdel Fattah al-Sisi "a dog". The government passed a law last month banning protests not authorized by police in an attempt to end demonstrations by Islamists demanding the reinstatement of elected President Mohamed Mursi, who was removed by the army in July.
