Occupy Athens? Greece came to a standstill on Wednesday as the nation’s public sector called for a 24-hour strike, the first since June. Airports have closed, hospitals are being run by emergency staff, and lawyers and teachers did not show up for work. Instead, thousands of people took to the streets to protest the deep austerity measures that the Greek government has enacted in its ongoing quest to stem a sovereign debt crisis. In Athens, riot police fired tear gas at protesters and clashes broke out between the civil servants and security forces.
