On the night of 9 November, Russia's Leningrad region was attacked by 113 drones, according to regional governor Alexander Drozdenko.
Based on eyewitness videos, independent Russian media outlet Astra identified the Kirishi Oil Refinery (KINEF) as the target of the attack.
Following several powerful explosions, at least two fires broke out at the facility. One of the refinery's primary oil processing units reportedly caught fire.
KINEF is Russia's second-largest oil refinery, with a processing capacity of up to 21 million tonnes of crude oil per year. Owned by Surgutneftegas, the facility supplies petroleum products to northwestern Russia, including St Petersburg and Pulkovo Airport.
In addition to petrol, diesel and aviation fuel, the refinery produces fuel oil, bitumen, liquefied gas and petrochemical products.
The refinery has been repeatedly targeted by drone attacks in 2025–2026. Following a strike on 30 August 2026, the facility completely suspended oil processing operations due to damage to two primary refining units.
