How did tens of thousands of Ukrainian children end up in Russian re-education camps? Peter Beaumont reports
Ukrainian officials say 16,000 children have been deported from Ukraine to Russia, but some estimates are much higher.
In March, the international criminal court issued arrest warrants for Vladimir Putin and Russia’s children’s commissioner, Maria Lvova-Belova, alleging they were responsible for the “war crime of unlawful deportation” of children.
