Demonstrators supporting former president Mohamed Mursi marched to Nahda Square in front of Cairo University on Sunday evening to demand Mursi's return to power, the Middle East News Agency reported.
The pro-legitimacy masses chanted "Leave, Sisi ... Mursi is my president" and said they will stage a sit-in in the square until their demands are met.
Thousands marched from the nearby Faculty of Applied Arts to the square and chanted "Mursi... Mursi" as they carried their shrouds.
A march grouping thousands of women also joined the mass demonstration.
In Qena, thousands of pro-Mursi Islamists organised a demonstration in Sa'aa Square to back the former president's legitimacy.
