A fresh wave of Ukrainian drone attacks has ignited a fire at Russia's Syzran oil refinery in the Volga region, marking another strike on the country's energy infrastructure as Moscow continues to grapple with fuel supply disruptions.
The refinery, operated by state-owned Rosneft, was reportedly hit during overnight attacks that also left one person dead and three others injured, including a child, according to Samara regional Governor Vyacheslav Fedorishchev.
While the governor confirmed that residential buildings and an industrial facility sustained damage, he did not identify the affected industrial site. However, independent Russian news outlet Astra, citing videos and photographs circulating on social media, identified the damaged facility as the Syzran refinery, where multiple fires were seen burning.
Russia's Defence Ministry said its air defence systems intercepted 349 Ukrainian drones overnight, reflecting one of the largest waves of drone attacks recorded in recent days.
The Syzran refinery has repeatedly been targeted since the conflict escalated. A previous drone strike in late May forced the facility to halt operations temporarily.
With an annual refining capacity of approximately 8.5 million tonnes, the refinery is a key producer of petrol, diesel and kerosene for the Russian market.
The latest attack comes as Russia faces mounting pressure on domestic fuel supplies following months of Ukrainian strikes on oil refining infrastructure. The repeated disruptions have reduced refining capacity, leading some petrol stations to introduce fuel rationing, while motorists in several areas have experienced long queues to purchase fuel.
Ukraine has increasingly targeted Russia's oil and fuel infrastructure as part of a broader strategy aimed at weakening Moscow's logistics and economic capacity while increasing pressure on the Kremlin to negotiate an end to the conflict.
For its part, Russia has maintained that any future peace agreement must include the transfer of Ukrainian territories claimed by Moscow, including areas that remain outside Russian military control more than four years after the full-scale invasion began. The two sides remain divided over the conditions for a negotiated settlement, with Russia insisting that any peace agreement must include the transfer of Ukrainian territories claimed by Moscow.
