Overview
- Ukrainian security services said drones hit the Kirishi refinery and a nearby pumping station overnight Monday to Tuesday, igniting fires.
- The SSU reported strikes on three primary AVT units at the plant and on a fuel tank at the station, noting these units start crude oil distillation.
- NASA’s FIRMS data flagged heat anomalies at Kirishi, and the regional governor reported a localized industrial fire without confirming a direct hit on the refinery.
- The refinery, run by Surgutneftegas and capable of about 20–21 million tonnes a year, may have been offline since late March, according to a source cited by Bloomberg.
- Ukraine framed the operation as choking funds for Russia and said the Kirishi station feeds exports through Primorsk, while also reporting a separate strike on the VNIIR Progress plant in Cheboksary.
