Ukraine confirms drone strike on one of Russia's biggest, most modern oil refineries near St. Petersburg

Ukrainian drones struck an oil refinery in Kirishi, in Russia's Leningrad region, overnight Oct. 4, sparking a fire that was later extinguished, Ukraine's General Staff has said.
Eyewitnesses reported seeing the fire break out at the Kirishi refinery. Regional Governor Alexander Drozdenko confirmed the drone attack and fire but did not identify the facility, adding the fire had been extinguished.
"Air defense forces destroyed seven UAVs in the skies over Kirishi. The fire in the industrial zone has been extinguished," Drozdenko wrote on Telegram.
Video and photos published by Astra, an independent Russian news channel, appeared to show a large explosion and flames rising from the refinery. The strike was later confirmed by the General Staff in a post on social media.
The Kyiv Independent could not verify the reports.
The refinery, more than 800 kilometers (500 miles) from Ukraine's border, is one of Russia's largest, was only opened in 2017, and accounts for 6.6% of Russia's total oil refining volumes.
It has been targeted at least three other times — in September and March this year and in March 2024.
Russia's Kirishi oil refinery near St Petersburg had a difficult night, continuing to burn into the morning.

Ukraine's military previously claimed responsibility for the September and March 2025 strikes as well.
Just a day earlier, Ukrainian drones targeted a chemical plant in Russia's Perm Krai, briefly disrupting production at one of the country's largest nitrogen fertilizer producers, which also supplies chemicals used in explosives. Separately, Ukrainian drones attacked an oil refinery in Russia's Orenburg Oblast on the same day.
Ukrainian forces have intensified attacks on Russia's oil industry and other parts of its military-industrial complex over the past year, disrupting operations and worsening a nationwide fuel shortage.
Kyiv considers Russian oil refineries to be legitimate military targets that fund and fuel Moscow's war effort.
