Russian gymnast Ivan Kuliak was seen wearing a pro-war symbol on his leotard while standing next to a Ukrainian opposition on the podium at Apparatus World Cup in Doha, Qatar.
Kuliak who won the bronze medal in the parallel bars event, displayed a letter 'Z' taped to his chest, as he stood next to Ukrainian gold medallist Illia Kovtun.
The letter Z has become of Russia's invasion of Ukraine and has been seen painted on military tanks and vehicles, as well as pro-war Russian politicians.
The International Gymnastics Federation (FIG) has said that it will be opened a disciplinary investigation against Kuliak for his 'shocking behaviour' at the international event.
This was both Russia and Belarus gymnast's last chance to compete in international tournaments, after being banned by FIG, as a result of the invasion on Ukraine.
Going forward, Russian and Belarusian athletes, officials and judges won't be allowed to take part in any FIG competitions, until further notice.
