What happened

Ukraine's General Staff said its forces struck the restricted Prioritet facility in Borok during operations on 27 July and overnight into 28 July. It described the Rosrezerv site as a strategic state oil depot used for long-term storage of fuel, petroleum products and lubricants for emergency and military requirements. Russian regional authorities reported intense air-defense activity but did not publish a facility-level damage assessment. Public imagery and OSINT accounts reported a fire, but the extent of damage and any operational effect remain unverified. The marker is approximate.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
