Police forces used teargas to disperse groups of protesters who back deposed President Mohamed Mursi and the Muslim Brotherhood in Maadi, Gesr al-Suez, and Zeitoun areas in Cairo, in addition to Mohandessin and Talebiya in Giza on Friday.
In Maadi, security forces fired teargas bombs at a pro-Brotherhood march to break it up.
They deployed three armoured vehicles in Ahmed Zaki Street in Maadi after supporters of the Brotherhood staged a march without obtaining a permit as per a new protest law, the state-owned agency MENA reported.
Clashes broke out in Gesr al-Suez and Alf Maskan areas between Mursi supporters and the police as the latter dispersed a march for Mursi's allies using teargas.
In Zeitoun, clashes erupted when pro-Brotherhood demonstrators chanted anti-army slogans, which prompted residents of Ezbet Shaheen to fight with them.
Security forces broke up a march in Giza's Talebiya using teargas, which led the pro-Mursi demonstrators to clash with them.
Earlier today, police tear-gassed pro-Mursi protesters in Mohandessin's Ahmed Orabi Street after the latter hurled stones at security forces.
