Cairo's Tahrir Square, the epicentre for Egypt's contribution to the Arab Spring, has once again become a flashpoint in a country that appears to be struggling with its transition from the rule of former president Hosni Mubarak.


Tens of thousands have been cramming the square demanding the country's interim military rulers immediately transfer power to a civilian government, a demand that was met today by Egypt's top official floating the idea of a referendum.
