Photo Gallery: Egypt revisited by turmoil
Since the 2011 Revolution, Egyptians have become familiar with outbursts of violence across the nation. The public is polarised and political groups have been locked in an impasse since December. Presidential calls for dialogue have largely been ignored by the opposition.
The most recent surge in violence hit hardest in the cities overlooking the Suez Canal; Port Said, Ismailia, and Suez, where dozens have been killed since Saturday in addition to hundreds injured. President Mohamed Morsy declared a state of emergency and a curfew in the three cities and tanks have been deployed.
However thousands have protested at night in defiance of the curfew. Downtown Cairo has also had its share of violence with police intercepting several marches attempting to reach the Shura Council.
