Gymnast Ivan Kuliak stunned officials and fans on Sunday when he appeared to support Russian forces invading Ukraine at the Apparatus World Cup in Doha, Qatar.

Kuliak, a 20-year-old artistic gymnast from Kaluga, Russia, finished in third place in the parallel bars at the event and joined Ukrainian Illia Kovtun and Kazakh Milad Karimi on the podium. Kuliak was seen sporting a "Z" on his chest in an apparent show of support for the Russian military.

As Russian forces began to move into the country last month, some tanks and other vehicles were marked with a white "Z." The symbol has been said to identify the vehicles as friendlies for Russian forces.

The International Gymnastics Federation (FIG) condemned the apparent show of support.
