Croatia beat hosts Russia on penalties in Sochi on Saturday following a 2-2 draw after extra time to book a spot in the World Cup semi-finals, where they will face England.

On Saturday night, a video showing Croatia defender Domagoj Vida shouting "Glory to Ukraine!" and Vukojevic saying "This is a victory for Dynamo [Kiev] and Ukraine" appeared on social media. Both of them previously played for Dynamo.

On Monday, the Croatian Football Federation (HNS) suspended coaching assistant Ognjen Vukojevic from his duties at this summer's World Cup.

The HNS apologized for the Croatian delegation members' behavior, and Vida also expressed regret for his words.

"I think, our Croatian partners know better what happened. I'm sure, they talked to the players and made a decision which was necessary in the given circumstances. We took it into account," Dvorkovich told journalists.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the final set to be played at Moscow's Luzhniki Stadium.
