An adviser to Ukrainian president Volodymyr Zelensky has likened Russian troops to Isis militants after they allegedly shared a video of a captive Ukrainian soldier to demand a ransom from his family.
Mykhailo Podolyak, a senior aide to the Ukrainian president, said Russian forces demanded €5,000 (£4,204) from the mother of a captured Ukrainian soldier if she wanted to see him alive. The Russians reportedly threatened to send a video of his execution if she did not pay the ransom.
