Protests at Cairo's Tahrir Square and other cities across Egypt on July 8 drew hundreds of thousands back to the streets to "save the revolution".
The protests are part of the ongoing struggle to press for democracy in the aftermath of the popular uprising that overthrew dictator Hosni Mubarak in February.
The protests, labelled “Friday of Justice for Revolution Martyrs” by the Facebook group We are all Khaled Said, has also been dubbed “Persistence Friday” in the media.
