The Croatian government issued a statement on Thursday condemning hate speech, offensive chanting and symbols and slogans of totalitarian regimes that had been used by Croatian fans at a friendly football match between Croatia and Israel.
The government called on citizens to respect the democratic values and not to undermine the country's reputation.
The Croatian Helsinki Committee on Human Rights also warned of inappropriate chanting during the match, played in the eastern city of Osijek on Wednesday.
Croatian fans chanted "For the Homeland Ready!", a salute used by the Nazi-style Ustasha regime that ruled Croatia during the Second World War.
