Police have made arrests after anti-capitalist demonstrations in Berlin left several injured, an official said early Sunday, DPA reported.
Clashes broke out after demonstrators reportedly threw stones and bottles against police cars, and set off various incendiary devices.
A police spokesman confirmed there had been injuries and arrests, but did not provide any figures.
The protest, estimated at 800 people by witnesses and 400 by police, was apparently held to commemorate the 10th anniversary of the death of another anti-capitalist activist.
Carlo Giulani, 23, was killed in July 2001 during clashes at the Group of Eight summit in Genoa, Italy. A judge ruled that the policeman who shot him was acting in self defence as Giulani approached his vehicle holding a fire extinguisher in the air.
