German police say they used water cannon and batons to disperse a group of violent protesters on the sidelines of a far-right march in Germany.
Police in the western city of Dortmund said they moved in after members of a roughly 1,000-strong group of "left-wing extremists" attacked officers and police vehicles Saturday.
Thousands of demonstrators had turned out in Dortmund to protest against a planned march by far-right supporters. Police said about 400 people turned out for the far-right event.
Confrontations between extreme-right marchers and counter-protesters are a regular event in Germany, though the far right is politically marginalized in the country.
