The Football Union of Russia has issued a statement urging the country’s fans to improve their behaviour.

The statement was released after UEFA confirmed it was opening disciplinary procedures following incidents during Russia’s opening Euro 2012 match against Czech Republic in Wroclaw on Friday.

On Saturday, anti-racism campaigners said monkey chants were directed at Czech defender Theodor Gebre Selassie during the game.

The Football Against Racism in Europe (FARE) group said an observer had heard “fleeting” abuse of the player. FARE chief executive Piara Powar, asked whether the abuse had included monkey chants, said: “Our observer reported descriptions of that nature.”

Violence also marred the match when stewards were attacked by a group of fans in a walkway.

Police spokesman Mariusz Sokolowski said the attackers were “from the group of Russian language fans,” adding: “We are trying to identify them. Police have the security footage from the stadium. We are looking into it.''

The Football Union of Russia statement said: “We appeal to all fans who are in Poland: remember that you represent your country. Respect yourself, your home and your team.”

UEFA confirmed that it had started disciplinary action, with its Control and Disciplinary Body to review the case on June 13.

“Having looked at the security reports and available images, UEFA has announced that disciplinary proceedings have been opened against the Football Union of Russia [RFS] for the improper conduct of its supporters, the setting off and throwing of fireworks, and the display of illicit banners at Friday's UEFA match,” a UEFA statement said.

Russia’s next match is against Poland in Warsaw on Tuesday.
