A senior NATO military official tells Bloomberg that Russian forces suffer more than 50,000 casualties during September, including as many as 28,000 troops killed. The official also estimates Ukraine’s losses during the same period at around 5,000 casualties. The figures are presented as estimates and are not independently verified in the reports.

Multiple outlets repeat the same NATO-based breakdown, framing it as a comparison of the scale of losses between Russia and Ukraine over one month. While the reported casualty estimates differ in magnitude—Russia’s losses being far higher than Ukraine’s—the coverage converges on the attribution to NATO and the lack of independent confirmation. The reports do not provide details on specific battles or methodologies beyond the NATO official’s assessment.

Overall, the outlets present the casualty numbers as part of the broader information environment around the war, emphasizing that the claims come from a NATO official and should be treated cautiously due to verification limits.
