A man carrying a knife attacked a demonstration organized by a far-right group in one of the central squares in the German city of Mannheim, wounding a number of people, including Michael Sturzenberger, an anti-Islam activist.
It was reported that a police officer was among the people who were stabbed, on Friday, in the market square of the city in southwestern Germany.
The police said that a firearm was used against the attacker, wounding him, adding that emergency services, additional security forces, and a rescue helicopter were immediately deployed.
Videos circulating from the scene show civilians trying to subdue the attacker, and in the end a policeman shot the suspect while he was wrestling with another man.
Police said in an online statement that they could not immediately provide details on the number of victims or the severity of the injuries.
Michael Sturzenberger was scheduled to speak at the event, but PAX Europe said he was among those injured.
The suspect stabbed two people first, then stabbed the police officer, and after he did not respond to the warnings given to him by the police, he was shot.
