Chmerkovskiy, who immigrated to the United States from Ukraine with his family in the 1990s, posted two new videos to Instagram Friday from Kyiv, where he was currently working on the reality competition series "World of Dance UA," according to his representative.
"I'm out here, again, I'm safe. We haven't been told to move, and I'm just following instructions. That's all I can say," Chmerkovskiy began the first clip. "But the reality is that I'm also talking to my friends that are here, the Ukrainians, and the situation is pretty dire."
"People are being mobilized" in Ukraine, Chmerkovskiy added. "The whole country is being called to go to war. Men, women, boys ... are going forward and getting guns and getting deployed to defend the country."
Chmerkovskiy also shared a video on Instagram Thursday, following Russia's invasion, in which he said he wanted to return to the US and realized that he has a way to because of his American passport.
"What I'm realizing is that my friends whose kids are here, whose moms, dads are here and elderly people who are here, they can't just escape," Chmerovskiy said emotionally.
He first began performing with the hit ABC dance competition series during Season 2 in 2005. He won the competition in 2014 also served as a guest judge the following year during season 21.
