Croatia manager Ante Cacic has described the fans who threw flares onto the pitch in their Euro 2016 draw with the Czech Republic as "sports terrorists".
The Group D match, which ended 2-2, was halted in the 86th minute when flares from the Croatia end rained down on the Saint-Etienne pitch.
"They are not really Croatia supporters. These people are scary and I call them hooligans," Cacic told reporters after the game.
"The 95% of Croatian supporters are ashamed in front of Europe. These are sports terrorists.
"This is maybe just a question about six to 10 individuals. I hope they can be identified and punished. I hope the Croatia FA is doing everything to prevent this, but it is impossible to avoid."
UEFA has confirmed that it will investigate the incident.
