Supporters of deposed President Mohamed Mursi staged several marches on Friday in Cairo and several cities to voice their support for Mursi whose trial is expected to take place on Monday.
The trial of Mursi and several Muslim Brotherhood leading figures is scheduled for next Monday.
The charges include inciting violence during clashes between supporters and opponents of the Brotherhood at the presidential palace on December 5. Eleven people, including Journalist al-Husseini Abu Deif, were killed while hundreds were injured in these clashes.
In Cairo, allies of Mursi marched from mosques in Helwan, Maadi, and Nasr City, the Middle East News Agency (MENA) reported.
A march for Muslim Brotherhood supporters headed from Maadi and Helwan on its way to the Ittihadeya presidential palace in Cairo's Masr al-Gedida, MENA added.
In Giza, Mursi supporters arranged marches from al-Mahrousa and al-Istiqama mosques. They carried banners with the Rabaa symbol and chanted slogans calling for the return of Mursi to power.
Police forces sealed off Mostafa Mahmoud and Nahda squares in anticipation of marches that might head to these squares.
In Alexandria, an eyewitness reported the outbreak of limited clashes between a pro-Mursi march on one hand and Alexandria residents and police forces on the other.
The police arrested a number of Brotherhood supporters after they were found in possession of what the police called anti-Armed Forces leaflets.
