The Croatian Karate Union has staged a national event for more than 600 competitors, under coronavirus restrictions in the Medjimurje region.
The World Karate Federation (WKF) said the event was the latest initiative by an organisation which was aimed at resuming the sport amid the COVID-19 pandemic.
Known as the Medjimurje Open, it was the first major karate event arranged in Croatia since the pandemic began earlier this year.
More than 600 athletes from 70 clubs were said to have participated in the event.
Organisers were required to meet requirements introduced by the Croatian Government to allow the competition to take place.
The WKF said the event was adapted to ensure the requirements were met.
Croatian Minister of Sport and Tourism Nikolina Brnjac was among those present at the Medjimurje Open.
Organisers have claimed the event was a success and could be considered an "example" for future sporting competitions held in Croatia under coronavirus regulations.
The event also saw Croatia's top young karate athletes receive prestigious "Drazen Petrovic" awards, named after the late Croatian basketball player.
Organised by the Croatian Olympic Committee, these annual awards recognise the most promising athletes in the country.
