Protesters and police clashed on Qasr al-Nil Bridge, around Tahrir square, in Cairo, Egypt, on January 27, 2013. Police and some supporters of President Mursi tried to evict the young revolutionnary activists from this emblematic place. At least 20,000 protesters take over Qasr al-Nil Bridge, connecting Giza to Tahrir Square in downtown Cairo. Police fired hundreds of tear gas canisters which protesters picked up and threw them back at police and into the Nile. Plumes of smoke could be seen all the way from Downtown Cairo.
