Around 20,000 people are marching in Erfurt, Germany on Saturday to protest against the far-right Alternative for Germany party's annual conference.
Antifascist protesters are blocking roads and tram lines around the city as riot police keep a watchful eye on proceedings.
"We want a society based on solidarity: equal rights, equal security, the right to residence and social security for all," Noa Sander, a spokesperson for the anti-AfD group Widersetzen, said. "That is what we stand for together here in Erfurt today".
Thüringen police described the protest as "legitimate" but said an AfD constituency office and police officers had been attacked with paint bombs and fireworks.
The conference nevertheless began as scheduled, the force later added in a post on social media.
