Analysis: There are signs the invaders are reaching exhaustion, but can the defenders cope with their military losses?
Three and a half months into the Ukraine war and what was once a fight across the whole country feels like it has become concentrated on Sievierodonetsk, the centre of weeks of combat that looks likely to have cost hundreds of lives as Russia appears to be closing in.
Ukrainian insiders estimate that Russia now has 120 battalions inside Ukraine, but such has been the attrition so far, their strength is perhaps 40% or 50% of a normal full compliment of around 800. Half that total force are concentrated in the eastern Donbas region – and a third, so 40, around Sievierodonetsk.
