Insights into Pentagon leaks and Russian infighting over Ukraine war death toll.

Leaked US documents reveal that disagreements in Russia's security apparatus led to the defence ministry being accused of undercounting casualties of the war in Ukraine. The files show the FSB security service claimed officials were not counting deaths of the Russian National Guard, Wagner mercenaries and others. Russia has already warned the leaks may be fake, deliberately dumped by the US. However, the detail corroborates what was already widely known: that Russia's military and security groups have had frequent disagreements about the handling of the war in Ukraine and that Russia has avoided publicising the numbers of dead and wounded.
