During the Russo-Ukrainian War, Russia has forcibly transferred almost 20,000 Ukrainian children to areas under its control, assigned them Russian citizenship, forcibly adopted them into Russian families, and created obstacles for their reunification with their parents and homeland. The United Nations has stated that these deportations constitute war crimes. The International Criminal Court (ICC) has issued arrest warrants for President of Russia Vladimir Putin (who has explicitly supported the forced adoptions, including by enacting legislation to facilitate them) and Children's Rights Commissioner Maria Lvova-Belova for their alleged involvement. According to international law, including the 1948 Genocide Convention, such acts constitute genocide if done with intent to destroy, in whole or in part, a nation or ethnic group.
Ukrainian children have been abducted by the Russian state after their parents had been arrested by Russian occupation authorities or killed in the invasion, or after becoming separated from their parents in an active war zone. Children have also been abducted from Ukrainian state institutions in occupied areas, and through children's "summer camps" on Russian territory. The abducted children have been subject to Russification; raising children of war in a foreign nation and culture may constitute an act of genocide if intended to erase their national identity.
