Russia likely behind lead of US military document: US officials in anonymity

Russia or pro-Russian elements are likely behind the leak of several classified US military documents posted on social media that offer a partial, month-old snapshot of the war in Ukraine, three US officials told Reuters on Friday.

The documents appear to have been altered to lower the number of casualties suffered by Russian forces, the US officials said, adding their assessments were informal and separate from an investigation into the leak itself.

The US officials spoke on condition of anonymity given the sensitivity of the matter and declined to discuss the documents in any detail.
