The Ryazan oil refinery, a major Rosneft facility that supplies fuel to Moscow, shut down operations after a drone attack on September 6, according to industry sources cited by Reuters. The refinery had previously been struck by drones in May and July, making this the latest in a series of attacks on the facility. Reuters later reported that damaged equipment at the refinery will take several weeks to repair, prolonging the disruption to fuel supplies. The strikes are part of Ukraine's sustained campaign against Russian energy infrastructure, aimed at degrading the country's oil-processing and military-logistics capacity.
