Al Jazeera’s Sherine Tadros, reporting from Tahrir Square, said the crowd of anti-SCAF protesters had been swelling after the Friday prayers.
“There are also protests in other cities, in Suez and Alexanderia. Lots of different demonstrations, but one clear message: that the SCAF needs to hand over power to civilians.
"They are also saying the recent violent crackdown, specially the violence soldiers used against women, is unacceptable."
A competing rally of several hundred people gathered in support of the military in another part of Cairo on Friday.
Al Jazeera’s Jamal el-Shayal, reporting from Abbasiya, said the protesters believe that it is only through the military establishment that some sense of stability can be restored.
"What will be interesting will be to see how the security forces deal with these protesters in comparison to those in Tahrir. Many people point to how there is a double standard."
