Disturbing amateur video has emerged showing Russia fans attacking stewards after their team's opening European Championship match in Poland.

A police spokesman said four of the stewards were taken to hospital after the clashes but were not badly injured.

The incident happened in a concourse area of Wroclaw Municipal Stadium, following Russia's 4-1 victory over the Czech Republic.

A witness told AP Television the Russian fans became aggressive when a steward identified one supporter who had thrown what was believed to be a flare.

No arrests were made, but police were examining security camera footage.

UEFA released a statement on Saturday calling it "a brief and isolated incident involving a small group of around 30 fans who attacked a handful of stewards. The situation was quickly and efficiently brought under control. The local police are aware of the incident and are investigating."
