Ukraine has launched fresh long-range drone attacks targeting two oil refineries deep inside Russia, triggering massive explosions and sending a huge plume of smoke over a Russian city. The strikes are the latest in Kyiv's campaign to disrupt Russia's fuel infrastructure as the war between the two countries continues. Ukrainian President Volodymyr Zelenskyy said the military would continue carrying out long-range operations aimed at weakening Russia's war capabilities, while Russian authorities confirmed damage to energy infrastructure and emergency response teams were deployed. Key Highlights Ukraine targets two Russian oil refineries in overnight drone attacks. Massive smoke plume seen rising over a Russian city. Russia confirms attacks on energy infrastructure. Zelenskyy says Ukraine will continue long-range military operations. The strikes are part of Ukraine's strategy to disrupt Russian fuel supplies. No immediate reports of casualties have been officially confirmed. What Happened? According to Russian officials, Ukrainian drones struck two oil refineries, causing fires and thick black smoke visible from several kilometres away. Videos circulating on social media showed large flames and a massive smoke plume rising above industrial facilities as firefighters rushed to contain the blaze. Authorities temporarily restricted access to the affected areas while emergency services worked to control the fires. Why Is Ukraine Targeting Oil Refineries? Ukraine has increasingly targeted Russian oil depots, refineries, and fuel storage facilities to weaken Moscow's military logistics. Oil refineries play a crucial role in supplying fuel for military vehicles, aircraft, and transportation networks. By disrupting these facilities, Ukraine aims to reduce Russia's operational capacity. The attacks also carry economic significance, as Russia remains one of the world's largest oil exporters. Russia-Ukraine War: Recent Escalation The latest strikes are part of an intensifying pattern of cross-border drone attacks between the two countries. In recent months, Ukraine has expanded its long-range drone capabilities, allowing it to hit military and energy infrastructure hundreds of kilometres inside Russian territory. Russia has simultaneously continued missile and drone attacks across Ukrainian cities. Timeline 2022: Russia launches its full-scale invasion of Ukraine. 2023–2025: Ukraine increasingly targets Russian military and energy infrastructure using long-range drones. Recent Months: Drone strikes on Russian oil depots and refineries become more frequent. Latest Update: Ukraine hits two Russian oil refineries, triggering massive fires and a huge smoke plume over a Russian city. What Happens Next? Military analysts expect both sides to continue targeting strategic infrastructure as the conflict enters another phase of long-range warfare. Russia may strengthen air defence systems around key energy facilities, while Ukraine is likely to continue drone operations aimed at disrupting fuel supplies and military logistics.
