UN to investigate prison attack that killed dozens of Ukrainian prisoners of war

Next challenge is to get Russia and Ukraine to agree on terms of reference to investigate atrocity, says UN secretary general

The UN is setting up a fact-finding mission to investigate the killing of dozens of prisoners of war at a prison in a Russian-occupied region of eastern Ukraine that Moscow and Kyiv accuse each other of carrying out.

Antonio Guterres, the UN secretary general, told reporters he did not have authority to conduct criminal investigations but could conduct fact-finding missions, and terms of reference were being prepared for the governments of Ukraine and Russia to approve. The mission was set up in response to requests from Russia and Ukraine.
