Long-range drones from Ukraine have hit the Yaroslavl oil refinery, situated deep within Russia — a major energy hub that processes 15 million tons of crude oil each year, supplying gasoline, diesel, and jet fuel for the Russian armed forces. This attack, validated by Ukraine's General Staff, focused on infrastructure nearly 900 kilometers from the Ukrainian border, showcasing the capabilities of Ukraine's homegrown drone technology. Kyiv has positioned this effort as a financial offensive against Russia's oil income, which it claims is directly funneled into military armaments.
