The head of the Serbian football association threatened to pull the team out of the European Championship over chants made during Wednesday's draw between Albania and Croatia.
Jovan Surbatovic, the General Secretary of the Football Association of Serbia [FSS], told Serbian broadcaster RTS that the country demanded action from authorities over remarks made during the match, including the chant: "Kill, kill, kill the Serb".
Surbatovic told RTS the FSS would seek sanctions from Uefa "even at the cost of not continuing the competition."
Meanwhile, Uefa, the governing body of European football, said it has opened a probe into the matter.
An ethics and disciplinary inspector has been appointed to "conduct an investigation regarding potential racist and/or discriminatory conduct by supporters" during the match, a statement said.
A probe has also been opened in "relation to the alleged inappropriate behaviour of the Albanian Football Association [FSHF] player Mirlind Daku", the statement added.
Serbian media reported that Daku initiated vulgar chants against Serbs and Macedonians. (AFP)
