A video is circulating online showing suspected Russian soldiers filming themselves beheading a Ukrainian prisoner of war with a knife.
The Kremlin said the footage was “awful” and its authenticity needs to be verified.
In a leaked Pentagon document, US officials estimated there were 97 special forces members from NATO countries active in Ukraine at one point, including 50 British soldiers, the BBC and The Guardian reported.
The mass document leak could be a move by the United States to “deceive” Russia during its “special military operation,” its deputy foreign minister says.
