Un poliziotto arresta un manifestante durante degli scontri ad Atene

Riot police officers detain a protester during minor clashes in Athens, Wednesday, Oct. 5, 2011. At least 16,000 protesters converged in the Greek capital, and a crowd of about 10,000 gathered in the northern city of Thessaloniki, as Greek civil servants walked off the job on a 24-hour strike Wednesday, paralyzing the public sector in a protest over ever-deeper austerity measures.
