A major oil refinery in Moscow owned by Gazpromneft has been hit by a second drone attack in less than a week, with industry sources reporting that multiple processing units were damaged and several fires broke out across the facility.
Moscow Mayor Sergei Sobyanin announced Thursday via Telegram that the region had been targeted in what he described as a large-scale drone raid, with several of the unmanned aircraft striking the refinery. The same plant had already come under attack on June 16, which forced it to shut down operations.
According to industry sources, Thursday’s strike caused damage to the Euro+ combined oil refining unit, a facility that was brought online in 2020 as part of the refinery’s modernization effort. That unit includes a crude distillation section capable of processing roughly 140,000 barrels of oil per day — accounting for about 47% of the refinery’s total capacity — along with a catalytic reformer and a diesel hydrotreating unit.
Beyond the Euro+ unit, sources indicated that secondary processing units, pipelines connecting different parts of the plant, and other auxiliary equipment were also damaged. Storage tanks holding refined oil products were struck and caught fire.
Gazpromneft, the company that owns and operates the refinery, had not responded to a request for comment at the time of reporting.
The June 16 attack had already dealt a significant blow to the facility. During that earlier strike, one of the refinery’s two main crude distillation units — known as CDU-6, with a normal processing capacity of around 160,000 barrels per day, or 53% of the plant’s total output — was damaged and caught fire.
Sources said the refinery had been planning to bring the Euro+ unit back online midweek and operate at roughly half capacity while repairs were carried out on CDU-6. Thursday’s attack disrupted those plans.
The refinery sits in the southeastern section of Moscow and plays an important role in supplying fuel to the Russian capital. According to sources, the facility processed 11.6 million metric tons of crude oil in 2024 — equivalent to approximately 230,000 barrels per day — and produced 2.9 million tons of gasoline, 3.2 million tons of diesel, and 1.3 million tons of bitumen during that period.
