Police say 11 people were injured in a third consecutive night of clashes with protesters supporting squatters in Spain's northeastern city of Barcelona.

A Catalonia police spokesman said dozens of demonstrators burned several trash containers and vandalized shop and bank branch fronts in disturbances that dragged on into the early hours of Thursday in the city's Gracia district. He spoke on condition of anonymity in keeping with police regulations.

He said six officers and five protesters were treated for minor injuries. One person was arrested.

The demonstrators want squatters allowed back inside a vacant bank branch they occupied for years and used as a "community center" until they were evicted Monday. They have pledged to hold five nights of demonstrations
