Seven fans needed hospital treatment after a mass brawl between rival Turkish supporters at a wheelchair basketball match in Germany.
The game, played in the eastern German town of Zwickau, was part of the four-day European Champions Cup tournament.
Police say about 60 fans from the Istanbul-based clubs Besiktas and Galatasaray began attacking each other with knives and baseball bats.
While none of the injuries sustained by the Turkish supporters were serious, the incident caused the match to be cancelled.
There is a long history of hate between Besiktas and Galatasaray, with violence often marring games between the two clubs across a variety of sports.
This latest fracas is not the first time fighting has broken out between supporters of their wheelchair basketball sides.
Back in 2012, 10 fans were arrested after a clash during a game in Istanbul when supporters sprayed fire extinguishers at each other – police used tear gas to break up the fighting.
Madrid-based CD Ilunion eventually went on to win the European Champions Cup, beating German side RSV Lahn-Dill 71-45 in Sunday’s final.
