NATO says that up to 40,000 Russian troops have been killed, wounded, taken prisoner or are missing in Ukraine, said a senior military official from the alliance.

The North Atlantic Treaty Organization calculates the figure based on information provided by Ukrainian authorities and information obtained from Russia – both officially and unintentionally, the official said.

NATO estimates that between 7,000 and 15,000 Russian soldiers have been killed since the invasion began on Feb. 24. Using statistical averages from past conflicts that for every casualty roughly three soldiers are wounded, NATO analysts reach their total figure.
