Ukraine hits two oil refineries deep in Russian territory

What Happened

Ukraine struck two Russian oil refineries, Bashneft-Novoil in Bashkortostan (1,300 km from the border) and Slavneft-Yanos in Yaroslavl region (700 km away), in what President Volodymyr Zelensky described as an effort to limit oil revenues financing Russia's war. Zelensky also reported hitting two military patrol boats and shadow fleet vessels in the Black Sea. Yaroslavl Governor Mikhail Evraev confirmed a fire at Slavneft-Yanos following what he called the 'largest enemy drone attack,' with 93 drones shot down over the region, four people injured, and debris striking storage tanks. BBC Verify corroborated social media imagery of smoke plumes at the site. Bashkortostan authorities did not publicly comment. Meanwhile, Russian attacks killed at least 11 people in Ukraine: three in a drone attack on residential houses in Balakliya, Kharkiv region, according to the State Emergency Service (DSNS); two more in a drone strike at Lozova train station, per regional head Oleh Synehubov; five in strikes on Dnipropetrovsk region; and one from hits on two dry cargo ships in Odesa. Kherson city suffered a total blackout after a critical infrastructure facility was hit, with internet connectivity dropping to 31%, NetBlocks reported. The Russian military claimed to have intercepted 605 Ukrainian drones overnight and struck Ukrainian fuel, energy, transport facilities, and drone storage sites.

Key Actors

Why It Matters

The strikes demonstrate Ukraine's extended deep-strike capability—up to 1,300 km inside Russia—directly targeting oil infrastructure to undercut Moscow's war funding. The reciprocal attacks on energy and transport infrastructure, and resultant civilian casualties and blackouts, mark an escalation in the air war even as front lines remain largely static and diplomatic mediation efforts have stalled.

Watch For

Monitor Russian retaliation strikes, damage assessments and operational status of the refineries, further Ukrainian long-range drone sorties, and the restoration of electricity and internet in Kherson. Also track any diplomatic reactions or new mediation initiatives.
