Ukraine’s armed forces struck the Bashneft-Novoil refinery in Bashkortostan and the Slavneft-Yanos refinery in the Yaroslavl region, Zelenskyy said.
In a post on social media, Zelenskyy said Ukraine’s long-range sanctions had “once again worked to limit Russia’s oil revenues, which it uses to finance the war and the killing of Ukrainians.”
The Slavneft-Yanos facility in Yaroslavl, which is situated hundreds of miles from the Ukraine border and about 170 miles (274 kilometers) northeast of Moscow, is one of Russia’s biggest oil refineries. It has previously been targeted by Ukraine’s military throughout the conflict.
The facility employs more than 3,500 people and makes about 15 million tons of crude oil each year, according to its website. Its products include fuel for cars, jet fuel and a wide range of oils.
Mikhail Evraev, governor of the Yaroslavl region, said on Thursday that the region had faced its largest-ever drone attack, with air defense and electronic warfare destroying 93 drones.
“Falling debris hit the oil refinery’s storage tanks. Emergency services are working to extinguish the fire,” Evraev said via Telegram. There were no casualties, but four people sustained injuries, he added.
Russian forces, meanwhile, have increased the number of missile strikes on Ukrainian cities, likely seeking to exploit Kyiv’s shortage of ballistic missile interceptors.
