Paris Saint Germain and Istanbul Basaksehir players have walked off the pitch in protest during their Champions League match over an alleged racist slur made by a match official.
The Turkish club's players protested after their assistant coach Pierre Achille Webo was shown a red card in the 16th minute of the game.
Video footage emerged which appeared to show Webo accusing a match official of using racist language.
Footballers from both teams left the pitch in the 23rd minute of their final Group H fixture in Paris and the game was suspended.
French champions PSG said on Twitter: "After a red card is given by the referee to a member of opposition staff, discussions continue between players and staff of both teams with the referee.
"The Basaksehir players decide to go back to the locker room, the Parisians follow them."
Basaksehir posted a message on their Twitter account which read: "NO TO RACISM #Respect."
