Western nations in the UN Security Council have criticized Russia for interrogating, detaining and forcibly deporting Ukrainians to Russia.
At a Security Council meeting on Wednesday, a senior official of the Office of the High Commissioner for Human Rights said the organization has verified that Russian forces subjected Ukrainian civilians to so-called "filtrations." She described this as a system of security checks and personal data collection.
She also said that, according to credible reports received by the human rights office, the practice has resulted in numerous human rights violations.
US Ambassador Linda Thomas-Greenfield said the filtrations are aimed at identifying individuals Russia deems insufficiently compliant or compatible to its control. She also said those deemed threatening to Russian control are being deported.
Thomas-Greenfield said Russia is preparing for "an attempted annexation," and staging "sham referenda" which would create "a false semblance of legality and public support" in areas Russia is seeking to annex.
She urged Russia to accept a UN investigation, saying the forcible transfer or deportation of protected persons from occupied territory to the territory of the occupier constitutes a war crime.
Russia's UN Ambassador Vassily Nebenzia claimed that those Ukrainians went through a registration rather than a filtration procedure.
He said Western nations are trying to tarnish his country with its latest disinformation campaign.
