Turkish supporters making their way to the European Championship quarterfinal against the Netherlands on Saturday have been making the same nationalistic hand gesture that saw a Turkey player banned from the match.
Berlin police said on X on Saturday that the gesture was "massively shown" by the fans and they had therefore stopped their march and asked them to stop making it. Fans were asked to make their own way as individuals to the game -- as long as they had a ticket for it.
"When a lot of people are doing this gesture, it becomes a political demonstration and a football march is not political demonstration," police spokesperson Valeska Jakubowski told The Associated Press.
The fans were making a gesture that is used by Turkish nationalists and associated with the Turkish ultra-nationalist organization Ulku Ocaklari, which is more widely known as the Gray Wolves.
Jakubowski acknowledged that showing the gesture is not banned in Germany but confirmed that some arrests were made. The situation was developing, however, and she was unsure why some fans were detained.
Turkey defender Merih Demiral was banned for two games by UEFA on Friday for making the gesture after scoring in Turkey's round-of-16 win over Austria in Leipzig on Tuesday, an incident that led to a diplomatic row between Turkey and Euro 2024 host nation Germany.
The ban ruled Demiral out of Saturday's quarterfinal, which the Netherlands won 2-1 to progress to a semifinal against England.
The Turkish Football Federation joined Turkish government officials in denouncing the suspension.
Turkish President Recep Tayyip Erdogan changed plans to visit Azerbaijan so he could attend Saturday's match. He defended Demiral, saying on Friday the defender merely expressed his "excitement" after scoring.
Turkish "ultras" on Friday called on other supporters to make the same gesture during the national anthem before Saturday's game and can be expected to do it during the game.
