Fans of Ukrainian club Dynamo Kiev face an investigation from European football's governing body after being caught on camera wearing Nazi and KKK outfits.
The fans wore the far-right oufits to a match against Shakhtar Donetsk, which is widely referred to as Ukraine's version of the 'Clasico' - the hugely popular derby between Barcelona and Real Madrid in Spain.
Fans were seen wearing swastikas as well as white clothing and tall hoods, and some also wore masks, to the match last Friday (April 21).

Uefa is now investigating the incident which took place on Friday (April 21) and discussing measures which should be taken, according to Red Gol.
The association wants to impose sanctions to ensure this kind of racist expression does not happen again, at either league or national level.
Supporters of both sides were also seen with flares at the Olympic stadium.
The stadium is supposed to be used for the Champions League final for the 2017/18 season, and this incident has raised concerns about its security.
