Russia Today | Six policemen have been shot and injured in a suburb of the Greek capital Athens, local authorities say. The police arrived in the area after a rowdy crowd of about 150 people started throwing rocks at a bus and smashing the windows of a nearby shop. Riot police reportedly quelled the mutinous crowd. It is not clear what sparked the violence or who fired at the policemen. The western suburb of the Greek capital has been the scene of a number of clashes between its predominantly Roma population and the police.
