Barcelona - Police have clashed with gangs of hooded youths who threw rocks and set fire to trash containers in the third night of violence in Spain's north-eastern city of Barcelona. Twenty-five people have been arrested.
A police spokesperson said on Thursday the disturbances began after a peaceful protest the previous evening in the central Sants district of Barcelona when police prevented some protesters from approaching a town hall office. She spoke on condition of anonymity because of police rules preventing staff from being identified.
The demonstration, which drew supporters from around and outside the city, was to protest Monday's closing of a social centre that was occupied by squatters for 17 years.
