Kyiv was hit again, exposing the cost of the air-defense shortage.

Russia hit Kyiv overnight with ballistic missiles and drones, killing at least nine civilians and wounding 33, according to Ukrainian authorities cited by the Associated Press. The assault followed a major Russian barrage two days earlier that killed at least 10 people across Ukraine and sent a missile across the Polish border, prompting NATO aircraft to scramble. The immediate fact is devastation in Kyiv; the larger fact is that shortages of ballistic-missile defenses leave civilian protection and European deterrence tied to the same supply problem.

Russia’s overnight ballistic-missile and drone attack on Kyiv killed at least nine people and wounded 33. Coming after another broad assault and a missile crossing into Poland, it shows how a war of attrition can rapidly become a wider European security test.
