Three people died and 23 were hurt in Zeitoun , in western Cairo , and one person was killed and 17 injured in Manial in central Cairo , according to state media . The violence came during a pro-Morsy march in Cairo . Since Morsy 's ouster and detention in July , his supporters have taken to the streets most Fridays . His supporters were unable to reach Tahrir Square and the presidential palace , according to state-run Al-Ahram . Morsy 's son : 'Dad , you are the legitimate leader ' Compared with violence in August that claimed hundreds of lives , the latest clashes appeared almost minor . On Friday , an anti-Morsy politician was stabbed in Cairo . It was n't clear whether the attack was tied to the protests . State media reported that Khaled Dawoud sustained stab wounds to his chest and hand . Dawoud resigned from the government in August in protest of the bloody crackdown on Muslim Brotherhood supporters . The unrest came amid reports on state media concerning the fate of 170 imprisoned members of the Muslim Brotherhood . Nile TV reported that this group , including a former governor , will be held for 15 more days for further investigation . It was not clear how long this group had been held or on what charges . Since July , arrests and violence have been commonplace . In September , an Egyptian court banned all activities of the Muslim Brotherhood and froze its finances , drawing complaints from the international community . At the United Nations last week , Egypt 's interim foreign minister sought to quell these concerns . Nabil Fahmy said Egypt will hold elections in the spring . He also argued that the political process is open to all `` as long as they are committed to the renunciation of violence and terrorism and acts of incitement to them .
