But Western officials are warning that Russia’s invasion of Ukraine is turning into a “slow annihilation” of Ukraine’s military and that continued siege tactics will increasingly hit civilian targets. The warning comes as Russia is reportedly deploying heavier weaponry and greater numbers of troops.

Ukrainian officials are calling for even more immediate security aid from the West to keep defenses going.
