Ukrainian military says it hit oil refineries in two Russian regions

Ukraine's military said on Monday it had hit Russian oil refineries in two regions over the past two days.

Ukraine's general staff said on Facebook that the strikes had targeted a refinery in the Ryazan region and the Novokuibyshev refinery in the Samara region. It said both facilities supplied fuel for the Russian army.

"The Ryazan Refinery produced an average of 840 thousand tons of high-grade fuel for jet engines," the military's statement said, adding that the fuel had been used by Russian warplanes attacking Ukraine.

The statement said that fuel from the Novokuibyshev refinery was piped and brought via rail to Russia's armed forces in northern Ukraine.
