The International Olympic Committee has set standards for Russian and Belarusian athletes when they compete, but they are not enough for Ukrainian boxing legend Wladimir Klitschko.

Athletes from Russia or Belarus must compete under neutral status and have no military ties, and anyone who has shown support for the invasion of Ukraine is not allowed to compete.

But Klitschko, the brother of Kviv’s mayor, former boxer Vitali Klitschko, took to Twitter to criticize the IOC for allowing Ukrainian and Belarusian athletes to compete in the first place.

«The IOC authorizes Russian and Belarusian athletes to participate in the Olympic Games under ‘neutral flag’. This decision is a false flag…» he tweeted on Tuesday. «This decision contaminates the Olympic spirit and is like this war: nonsense.»

The official page of the Ministry of Defense of Ukraine tweeted: «The white flag of the Russian Olympic team is dripping with the blood of innocent Ukrainian civilians,» a post the 1996 Olympic gold medalist retweeted.

In February, Klitschko recorded a video pleading with IOC President Thomas Bach to ban athletes from those countries from competing, saying it would «portray the Olympic spirit» if he did.

Russian athletes were banned from playing in last year’s Wimbledon tennis tournament.
