Riot in Germany as Blockupy Anti-austerity Protestors and Police Clash

Police cars have been set on fire, windows smashed and stones thrown at police and firefighters at a demonstration timed to coincide with the opening of the new European Central Bank headquarters in Frankfurt.
Anti-austerity protesters were gathering in the city under the #blockupy and #18M hashtags to demonstrate against the so-called "Troika" of the ECB, the European Commission and the International Monetary Fund who oversee bailout packages in the eurozone.
So far 350 people have been detained, Frankfurt police said Wednesday morning.
