Violence flares in Barcelona as protests persist

The nine-month sentence of Pablo Hasel, known for his virulently anti-establishment raps, has sparked a debate over freedom of expression in Spain as well as protests that have at times turned violent.

About 6,000 demonstrators gathered in the city, local police said. They also said some were detained for looting.

Protesters attacked shops on Barcelona's most prestigious shopping street, Passeig de Gracia, while newspaper El Pais reported others had smashed windows in the emblematic Palau de la Musica concert hall.
