Verniaiev, a gymnast who won gold on the parallel bars in the 2016 Olympic Games in Rio, gave a peace sign in his uniform on his Instagram Stories on Tuesday.

Russia’s invasion of Ukraine, which began on February 24, has continued to push Ukrainians out of their country, devastating towns and cities, including Donetsk, where Verniaiev is from.

Verniaiev is not the only gymnast to join the ranks, as 18-year-old Ukrainian National Team gymnast Volodymyr Kostiuk announced two weeks ago that he received his draft notice and posted it on his Instagram, according to WOGymnastika, a gymnastics news source. Kostiuk wrote in Ukrainian: “Guess who is going to the military enlistment office tomorrow?”

Verniaiev has shown his online support for Ukraine since the start of the invasion and posted a call for Russia to be banned from all international sports on February 28.

Verniaiev wrote a list of demands in the post: “1. Exclude Russia from all sports international governing bodies (IOC, FIFA, UEFA, IIHF, IAAF, FIBA, ISU, etc.)”

“2. Ban any Russian athletes from participating in any international competitions,” he added. Third and fourth, he wrote, “Stop the sale of rights to broadcasts of international sporting competitions to Russian media” and “Prohibit Russian companies from being sponsors of international competitions and clubs.”

Finally, he asked the international sports society to “Support Ukraine with information! Join to sharing true information about actions of the aggressor countries!”

On the same day, FIFA and UEFA released a joint statement saying that Russian national and club soccer teams were banned from international competition, including the 2022 World Cup in Qatar.

Prior to FIFA’s statement, the International Olympic Committee called for Russian and Belarusian athletes to be banned from international competition until the crisis in Ukraine was resolved.

Russian teams have since been banned by the International Tennis Federation and even video game developer EA Sports, which no longer will include Russian teams in upcoming games. The National Hockey League suspended relationships with its Russian business partners.

Verniaiev also spoke out against Russian gymnast Ivan Kuliak, who wore the controversial Z symbol during competition and while standing beside Ukrainian competitor Illia Kovtun during the Artistic Gymnastics World Cup in Doha, Qatar.

“You’re sorry, of course, but let the Russians not shout that sport is out of politics! Congratulations to our guy, everything is in place Glory to Ukraine,” Verniaiev posted on Instagram on March 5.

Newsweek reached out to the International Gymnastics Federation for comment.
