Ukraine's General Staff said on Sunday that it struck a facility of Chornomornaftogaz near the village of Vnukovo in western Crimea, which it said may be the Glebovskoye underground gas storage facility, the only such storage on the peninsula.
The Ukrainian command also reported hitting a ground-based relay station for controlling Geran and Gerbera attack drones near the settlement of Chornomorske, saying the relay increased the range and stability of drone communications.
In addition, Ukrainian forces said they struck a road bridge near Vyselky in Donetsk region used by the Russian army for logistics, and in Luhansk region hit a drone storage site near Chervonopopivka and a concentration of Russian personnel in Purdivka.
There was no independent confirmation of the consequences of these strikes. NASA's FIRMS satellite fire monitoring system did not detect thermal anomalies in the specified areas.
Russia's Defense Ministry reported intercepting 133 drones over nine regions, the Moscow area, Krasnodar Krai, annexed Crimea, and the Black Sea. It did not specify how many were shot down over Crimea. Russian authorities did not report any hit on the Chornomornaftogaz facility. Overnight, residents of Chornomorske, Feodosia, Simferopol, and Alushta reported explosions and air defense activity.
The General Staff also confirmed an attack on the Tyumen oil refinery that occurred the previous day. Tyumen region governor Alexander Moor said a drone fell on the plant's territory, causing a fire that was extinguished, with no casualties. Ukrainian President Volodymyr Zelensky described such strikes as 'long-range sanctions.'
The Tyumen refinery is located more than 2,000 kilometers from the border with Ukraine. Its nominal capacity is about 8 million tons of oil per year, producing approximately 500,000 tons of gasoline and 2.5 million tons of diesel fuel. The attack interrupted Tyumen's City Day celebrations; after the alert was lifted, venues resumed work but the fireworks were canceled.
