A protest by hundreds of youth activists turned violent early Sunday, with protesters setting fire to street barricades and cars and smashing shop windows, police said. Officers used tear gas to disperse the crowd. One officer was injured and 63 people were arrested as riot police clashed with rock-throwing youth in the Noerrebro district of Copenhagen, police said. The unrest started after a demonstration late Saturday commemorating the Youth House, a makeshift cultural center for the city's anarchists and disaffected youth that was demolished in March, the Associated Press reported.
