Russia has suffered up to 40,000 casualties, and between 7,000 and 15,000 deaths, in Ukraine, a senior NATO military officer announced on Wednesday.
The term “casualty” includes all soldiers who have been injured, killed, or captured in battle.
Wednesday’s estimate is the first such figure released by NATO since the war started in late February.
Following NATO’s policy of anonymity, the military official’s identity has not been released. However, the official stated that the figure was calculated using information from Ukraine, public data, and indications from Russia, according to the Associated Press.

Fierce resistance by Ukraine has made what Russia may have believed would be a simple invasion into a full-scale war. Frustration at the current state of the war may have led Russian forces to target civilian infrastructure to weaken morale in Ukraine.
