Afresh diplomatic row has erupted over allegations concerning Ukraine’s treatment of detainees, after a Putin aide reportedly raised accusations against Kyiv at the United Nations. The remarks have added to the information battle surrounding Russia’s war in Ukraine, where Moscow and Kyiv have repeatedly traded allegations over human rights and the treatment of prisoners. Claims made by Russian officials require independent verification and should not be treated as established fact without supporting evidence. The controversy also raises questions about how Ukraine’s Western allies respond to accusations against Kyiv while continuing to support its defence against Russia’s invasion. What was alleged at the UN, and how have Ukraine and its partners responded?
