UEFA have opened disciplinary proceedings against both Spain and Russia over their supporters' behaviour at Euro 2012.

Both cases relate to racist behaviour and/or chanting which happened during the two sides' respective group games.

A UEFA statement read: "UEFA has opened disciplinary proceedings against the Royal Spanish Football Federation (RFEF) for the improper conduct of their supporters (racist behaviour, racist chanting) at the EURO 2012 Group C match against Italy in Gdansk on Sunday 10 June.

"Disciplinary proceedings have also been opened against the Russian Football Union (RFS) for the improper conduct of their supporters (racist behaviour, racist chanting) at the EURO 2012 Group A match against the Czech Republic in Wroclaw on Friday 8 June."

The cases will be dealt with on Thursday, a day after Spain's semi-final against Portugal.
