At least 7,000 Russian troops have been killed in Ukraine since Russia’s invasion 24 February, the CNN reported, quoting US and NATO officials.
According to the report, the heavy losses have made Russia struggling to resupply those forces as it faces sagging troop morale and fierce Ukrainian resistance.
Russia’s offensive to capture Kyiv has largely stalled, NATO officials said, and on Thursday Ukraine said it launched a counteroffensive aimed at gaining decisive control of the city’s suburbs.
US and allied intelligence assessments vary widely as to exactly how many Russian forces have been killed to date, sources familiar with the intelligence tell CNN.
But even the lowest estimates are in the thousands.
One such assessment found that approximately 7,000 Russian troops have been killed so far, said one of the sources.
But that figure, first reported by The New York Times, is on the higher end of US estimates, which vary because the US and its allies have no precise way of counting casualties.
Some estimates place the number of Russian troops killed in Ukraine at about 3,000, whereas others suggest more than 10,000 have been killed.
So far, the number has been calculated largely via open source reporting from non-governmental organizations, the Ukrainian government, commercial satellite imagery, and intercepted Russian communications.
US officials have also extrapolated numbers of dead based on the number of Russian tanks that have been destroyed, the sources said.
As the Russian advance on Kyiv stalled, Reuters reported that the war has settled into a grinding pattern of sieges of cities.
Ukrainian officials are reporting Russian attacks on schools, hospitals and cultural facilities.
The United Nations human rights office in Geneva said it had recorded 2,032 civilian casualties so far in Ukraine – 780 killed and 1,252 injured.
Some 3.2 million civilians, mostly women and children, have now fled to neighbouring countries, the United Nations said.
