Live updates: Esteemed theater director taken by Russians

Nebenzia warned that adoption of that resolution “will make a resolution to the situation in Ukraine more difficult.” That’s because it will likely embolden Ukrainian negotiators and “nudge them to maintaining the current unrealistic position, which is not related to the situation on the ground, nor to the need to tackle the root causes” of Russia’s military action, he said.

WASHINGTON — A senior NATO military officer says the alliance estimates that Russia has suffered between 30,000 and 40,000 battlefield casualties in Ukraine through the first month of the war, including between 7,000 and 15,000 killed. It is NATO’s first public estimate of Russian casualties since the war started Feb. 24.

The military officer, speaking on condition of anonymity under ground rules set by NATO, said the estimate of the number killed is based on a combination of information from the Ukrainian government, indications from Russia, and open-source information.

The U.S. government has largely declined to provide public estimates of Russian or Ukrainian casualties, saying available information is of questionable reliability.

The NATO military officer, in a briefing from the alliance’s military headquarters in Belgium on Wednesday, said the estimate of 30,000 to 40,000 Russian casualties is derived from what he called a standard calculation that in war an army suffers three wounded soldiers for every soldier killed. The casualties include killed in action and wounded in action, as well as those taken prisoner or missing in action, the officer said.
