Protesters marched against the Turkish military offensive in Syria's Afrin at a demonstration in Hamburg, Saturday.
Brief clashes broke out between protesters and unidentified persons. Police rushed in to keep the two sides apart, using tear gas to disperse the groups.
On January 20, Turkish President Recep Tayyip Erdogan announced the beginning of the military operation 'Operation Olive... Еще Branch' against the Kurdish YPG militia.
Turkey views the YPG, which is active in northern Syria, as an extension of the banned militant group the Kurdistan Workers' Party (PKK), whose leader is Abdullah Öcalan. Germany outlawed the PKK in 1993 and recognises the organisation as a terrorist group.
The German government has since banned PKK symbols including flags and portraits of the founder of the party, Abdullah Ocalan. Police were seen confiscating banned flags at Saturday's protest in Hamburg.
