Violent conduct before, during and after England's 1-1 draw against Russia in their Euro 2016 opener on Saturday marred the on-field proceedings in Marseille.

The European football governing body have on Sunday charged the Russian FA with crowd disturbances, racist behaviour and setting off fireworks, with further sanction set to be decided by Tuesday.

However, England and Russia have both been warned that either side could be thrown out of the competition should such occurences repeat itself in the coming days.

In a statement released on their official website, UEFA have expressed their "disgust" at the fans' behaviour and have voiced their support for the French authorities to fight against such acts of violence.

"The UEFA Executive Committee would like to express its disgust for the violent clashes which occurred in the city of Marseille," read the statement.

"Such unacceptable behaviour by so-called supporters of the national teams of England and Russia has no place in football, a sport we must protect and defend.

"The UEFA Executive Committee has warned both football associations that – irrespective of any decisions taken by the independent disciplinary bodies relating to incidents inside the stadium – it will not hesitate to impose additional sanctions on the Football Association (FA) and the Russian Football Union (RFS), including the potential disqualification of their respective teams from the tournament, should such violence occur again.

"We urge both the FA and the RFS to appeal to their supporters to behave in a responsible and respectful manner.

"We would also like to publicly voice our support for the work of the French authorities and security forces for their efforts to deliver a safe and secure tournament in challenging circumstances."

Russia will clash with Slovakia in their next Group B fixture in Lille on Wednesday, before England face Wales in Lens the following day.
