Ukrainian Illia Kovtun won the event in Qatar at the weekend, while Kuliak finished third, Polish state broadcaster TVP Info reported on its website.
As the athletes stood on the podium, Kuliak displayed the letter “Z” on the front of his outfit, a symbol that has been seen on Russian military vehicles taking part in the invasion of Ukraine, according to the tvp.info website.
The International Gymnastics Federation (FIG) said it would open disciplinary proceedings against Kuliak for his “shocking behaviour,” tvp.info reported.
