**Deck**: Ukrainian drones struck Russia’s Ryazan oil refinery, a Rosneft‑controlled plant that can process about 17 million tons of crude a year and supplies gasoline, diesel and aviation kerosene to regions around Moscow.

Ukrainian drones have struck deep inside Russia, hitting the Ryazan oil refinery and setting the facility ablaze. Ukrainian sources say the target was the Rosneft‑controlled plant, a large complex that produces gasoline, diesel and aviation kerosene and is a key supplier of motor fuel for regions around Moscow.

The refinery’s design processing capacity is about 17 million tons of crude per year, equivalent to roughly 340,000 barrels per day. It supplies fuel to both civilian consumers and the Russian military, making it a significant node in Russia’s energy and logistics network.

The Russian Ministry of Defense said air defense systems shot down 258 Ukrainian drones over Russian regions overnight and described the attack on the Ryazan Region as one of the largest in recent months. Near the refinery, a strike was reported close to the industrial area, followed by powerful explosions. Eyewitnesses spoke of an “oil rain” after the blast, while firefighters and emergency services worked at the scene.

Russian authorities have not publicly detailed the scale of damage at the refinery or how long any disruption might last. Even so, an attack on a plant of this size raises questions about the resilience of fuel supplies for both the military and civilians in the Moscow area.

For Ukraine, the strike demonstrates an ability to reach high‑value energy infrastructure far from the front line. For Russia, it underscores the challenge of defending extensive, flammable industrial sites against massed drone attacks.

Key developments to track now include any official assessment of damage at Ryazan, signs of shifts in regional fuel logistics, and whether Ukrainian forces continue targeting refineries and other energy facilities in Russia’s core industrial regions.
