March 17, 2024 - ISW PressThe Ukrainian State Security Service (SBU), Special Forces (SOF), and Unmanned Systems Forces reportedly conducted a successful drone strike against a Russian oil refinery in Krasnodar Krai on the night of March 16 to 17. Sources in the SBU told Ukrainian outlet Suspilne that the Ukrainian SBU, SOF, and Unmanned Systems Forces struck the crude oil atmospheric distillation columns of the Slavyansk oil refinery in Slavyansk-on-Kuban, Krasnodar Krai, resulting in a large fire.[8] Krasnodar Krai Operational Headquarters claimed that several drones attempted to strike the Slavyansk oil refinery and that Russian forces neutralized them, though falling drones caused a fire.[9] A Russian milblogger claimed that two of 17 drones that targeted the Slavyansk oil refinery struck the facility. Suspilne reported that SBU drones have recently successfully struck 12 oil refineries in Russia.[11] A Russian milblogger claimed that the Ukrainian strike on the Slavyansk oil refinery is the ninth Ukrainian strike on a Russian oil refinery in the past week. Another Russian milblogger claimed that Ukrainian strikes on oil refineries are more serious than strikes on fuel depots because international sanctions against Russia complicate Russia’s ability to repair technologically complex oil refinery facilities.
