About 8,000 people took part in subdued demonstrations in Athens as austerity-weary unions held a strike for May Day. The country’s main labor unions protested soaring unemployment, which is the highest in the 27-country European Union, and the austerity measures the conservative-led government is enacting in return for crucial bailout loans.(AP Photo/Petros Giannakouris)
