UEFA said Sunday that Russia and England could be thrown out of the European Championship finals if their fans are involved in more violence.

The UEFA executive committee said in a statement it has warned both countries that on top of any sanctions over trouble in Marseille this weekend, "it will not hesitate to impose additional sanctions on the Football Association (FA) and the Russian Football Union (RFU), including the potential disqualification of their respective teams from the tournament, should such violence occur again."
