Quote: "On the night of 19-20 November 2025, units of Ukraine's defence forces carried out a repeat strike on the Ryazan oil refinery in Russia's Ryazan Oblast as part of efforts to degrade the capabilities of the Armed Forces of the Russian Federation."

Details: Explosions occurred at the facility, followed by a fire in the area of the secondary oil-processing facilities. The precise consequences of the strike are being clarified.

The attack was carried out at a distance of more than 470 km from Ukraine's state border.

The refinery belongs to Rosneft, which plays an important role in supporting Russia's war effort. Its annual processing capacity is 17 million tonnes of oil (around 6.1% of total Russian refining). The plant produces diesel fuel and TS-1 jet fuel.

A strike was also recorded on a cluster of Russian personnel in the temporarily occupied territory of Donetsk Oblast. The number of Russian losses is being clarified.

Background: The Ryazan oil refinery suspended crude processing after a Ukrainian drone attack on 15 November.
