On Thursday, the Egyptian government turned off all mobile phone and Internet service. But despite the outage, Mohamed Ibrahim Elmasry - a professor emeritus of computer science at the University of Waterloo - found a way to update his Facebook page with dramatic videos of the protests taken from his apartment in Cairo.
Prof. Elmasry gave his permission to social media website Storyful to upload the videos to YouTube. The videos depict various stages of a confrontation between protesters and police on the Qasr al-Nil bridge.
