An estimate from the Yale School of Public Health puts the number of Ukrainian children that have been displaced or deported since the war began in the hundreds of thousands, including at least 6,000 who have been held in a series of Russian camps and ordered to undergo “re-education” programs to make their personal and political views more pro-Russia.

Russia operates at least 43 known facilities dedicated to providing “re-education,” military training, and pro-Russia academic instruction to Ukrainian children forcibly removed from their homes, the Yale report indicated.

Children who have been rescued from the camps describe being forbidden to speak Ukrainian, being forced to listen to the Russian national anthem repeatedly, and being lied to and told their parents had abandoned them, according to firsthand accounts collected by the “Children of War” project compiled by Ukraine’s Ministry of Reintegration of Temporarily Occupied Territories, established in 2016 following Russia’s annexation of Crimea.

In recent months, UN representatives of multiple countries have echoed Biden’s outrage, including Japan, China, the United Arab Emirates, and Albania.

Ferit Hoxa, Albania’s representative to the UN, called the deportations “an audacious bid to dismantle its future” of Ukraine, adding that Moscow “has failed to convince the world that its re-education camps and forced adoptions are, as portrayed, humanitarian actions” in an August statement.

Russia, which does not recognize the court’s authority, called the move meaningless and on Monday opened its own criminal cases against ICC prosecutors and judges, Politico reported.
