Pro-Nazi and anti-Semitic chants by Hajduk Split football fans ahead of their UEFA Conference League match against Ajax sparked outrage in Croatia while Israel's embassy voiced shock.
Groups of Hajduk Split fans, known as the Torcida, marched through the coastal town ahead of Thursday's match chanting: "Crush the Jews", "Rise up Adolf (Hitler)" and "Let's go Ustasha", referring to the country's World War II pro-Nazi regime, local media reported.
Dozens of fans were detained ahead of the match for violence. During the game Torcida fans set off flares and other pyrotechnics in the stands, forcing more than a 10-minute stoppage.
An investigation was opened into the pro-Nazi chants and so far three people have been arrested, suspected of "public incitement to violence and hatred", a police statement said.
On Friday, the country's leaders, opposition parties and rights groups as well as the Jewish community strongly condemned the incident.
President Zoran Milanovic in a statement labeled it "unacceptable and shameful".
He urged swift action against the perpetrators to "show that there is no place in Croatia for the glorification of Nazism and Ustasha ideology".
- 'Deeply shocked'-
Israel's embassy in Zagreb, in a statement obtained by AFP, said it was "deeply shocked by the serious anti-Semitic incident that took place in Split".
Conservative Prime Minister Andrej Plenkovic also condemned "messages of anti-Semitism ... completely at odds with the values we want to uphold in Croatian society".
Hajduk Split, who won the game 2-1, in a statement apologised to UEFA and Ajax who "witnessed scenes which we do not want Europe to remember", while the Croatian football federation joined in condemning the incident.
Croatia's ultra-nationalist hardcore supporters have tainted the country's image for years, notably by chanting pro-fascist slogans and displaying Ustasha symbols.
The regime killed and persecuted hundreds of thousands of ethnic Serbs, Jews, Roma and anti-fascist Croatians.
Croatia were docked a point by UEFA after their fans painted a swastika on the pitch in Split in 2015, ahead of a Euro 2016 qualifier with Italy.
The perpetrators were never found.
The leader of Croatia's Jewish community Ognjen Kraus said that he was not surprised by the incident "because it is a natural consequence of what has been going on for years".
His view was echoed by Croatian Serb leader Milorad Pupovac who told media that it was "only a matter of time" that something like that would happen.
In recent years, Croatia has seen a growing tolerance for its pro-Nazi past and critics accuse authorities of failing to sanction the use of Ustasha emblems.
