One of Russia's largest oil refineries has suspended operations after Ukrainian drone attacks earlier in the day, two unnamed oil industry sources told Reuters.
Parts of the Kirishinefteorgsintez refinery caught fire after the attacks. The refinery is located near the city of Kirishi, southeast of St. Petersburg.
Under normal circumstances, the refinery processes about 400,000 barrels of oil a day. On average, 18 million tons of oil have been processed annually at the refinery in western Russia in recent years. That corresponds to about seven percent of the total amount of oil refined in Russia.
On Thursday morning, there were reports of Ukrainian drone attacks targeting an industrial area near the oil refinery. According to Aleksandr Drozdenko, governor of the northwestern Leningrad region, where the oil refinery is located, more than 20 drones were shot down over the region. He wrote this in a post on the Telegram messaging service.
- The attack is being repelled over the Kirishi district. There is damage in the industrial area, the governor wrote.
However, he did not elaborate on which parts of the industrial area were damaged. It was also not clear whether there had been damage to the refinery.
This is not the first time that Kirishinefteorgsintez has been under attack. In 2025, the oil refinery was repeatedly targeted by Ukrainian attacks.
Russia's oil production is one of the country's most important sources of income. With a value of $2.6 trillion - around 16,800 billion kroner - it plays a central role in the Russian economy. Reuters wrote on Wednesday that at least 40 percent of Russia's oil export capacity has been put out of service.
This has happened as a result of Ukrainian drone attacks, an attack on a key pipeline and the seizure of tankers, it said. Two unnamed sources told Reuters that the Russian ports of Primorsk and Ust-Luga, both on the Baltic Sea, suspended loading of crude oil and oil products on Wednesday, citing Ukrainian drone strikes.
This is also said to have happened as a result of Ukrainian drone strikes.
