Strike drones attacked an oil refinery in the Russian city of Syzran, Samara region, on the night of March 4.
This was reported by Russian Telegram channels, including Baza and SHOT.
The attack on the facility became known around 1 a.m. Kyiv time. For the strikes on the oil refinery, PD-2 kamikaze drones were used, which have a maximum flight range of 1,100 km, as specified by Shot.
The Syzran oil refinery is owned by Rosneft. It produces 800,000 tons of gasoline and 1.5 million tons of diesel fuel annually. The facility has been attacked by Ukrainian drones three times before. The first attack occurred in March 2024, when a fuel processing unit caught fire. A second attack took place on February 19 this year, again causing a fire in the fuel processing unit, which led to the refinery halting production.
The Syzran refinery became the fourth plant to stop production in 2025 due to Ukrainian drone attacks. Earlier, the largest Rosneft plant, the Ryazan refinery, the Gazprom-owned Astrakhan gas processing plant, and the Lukoil-owned Vologda refinery also temporarily suspended operations.
Last year, due to drone attacks and repair issues, Russia’s oil refining volumes dropped to a 12-year low of 267 million tons. The export of oil products fell by 9%, to 113.7 million tons. In response, the government classified the statistics.
In the morning, the Governor of the Samara region, Vyacheslav Fedorishchev, confirmed the drone strike on a facility in Syzran, without specifying the name of the company, and stated that air defense allegedly shot down the drones. A fire also broke out, which continued into the morning. According to Astra, the drone hit the primary oil processing unit (AVT-6), where the fire spread over 30 square meters. Work at the facility was temporarily halted.
