Global protests mark May Day

Protesters across the world are taking to the streets to mark May Day, also known as Labor and International Workers' Day. In Greece, the atmosphere at Saturday's demonstrations was tense, with millions of people facing increased taxes and pay cuts as the government struggles to overcome its huge debt problem. Workers from Greece's two largest trade unions, Adedy and GSEE, marched through the capital, Athens, while workers belonging to the communist trade union, Pame, gathered in their thousands in front of the parliament building. Riot police fired tear gas as they clashed with dozens of youths, some armed with sticks, near the finance ministry. Skirmishes were also reported in other areas of Athens and in the city of northern city of Thessaloniki, where youths targeted cash machines and store windows with iron sticks.
