Serbia have threatened to quit Euro 2024 if UEFA fails to take action following alleged chanting between fans of Croatia and Albania.
A section of supporters attending the 2-2 draw in Hamburg on Wednesday could be heard taking part in offensive chants aimed at Serbia.
Jovan Surbatovic, general secretary of the Football Association of Serbia, has suggested Serbia may not continue at the tournament in Germany unless the European governing body hands down sufficient punishments.
Serbia play Slovenia in their second Group C match on Thursday in Munich.
“What happened is scandalous and we will ask UEFA for sanctions, even if it means not continuing the competition,” Surbatovic told Serbia state broadcaster RTS. “We will demand from UEFA to punish the federations of both selections.
“We do not want to participate in that, but if UEFA does not punish them, we will think how we will proceed.”
On Wednesday, UEFA cancelled the media credentials of a Kosovar journalist Arlind Sadiku for allegedly making a nationalist gesture towards Serbia fans during their game against England in Gelsenkirchen on Sunday.
