Ukrainian drones struck an oil refinery in Moscow for the second time this week, causing a large explosion and significant fire in the Kapotnia district. The attack occurred Thursday morning, with reports indicating flames and smoke visible across the Russian capital. This latest strike follows a similar incident earlier in the week, raising concerns about escalating attacks within Russian territory. Ukrainian officials have not directly claimed responsibility for either incident, though they have increased drone operations targeting Russian infrastructure. Russian authorities confirmed the attack and are working to extinguish the blaze, but details regarding damage and potential casualties remain limited. The attacks represent a growing challenge to Russia’s air defenses and a potential shift in the conflict’s dynamics.
