Overnight Ukrainian drone strikes damaged one of Russia’s largest oil refineries in the city of Yaroslavl, regional authorities said Tuesday.
Yaroslavl region Governor Mikhail Yevrayev confirmed that the local oil refinery was struck amid a “large-scale” attack, adding that two workers at the facility were injured. He did not provide details about the extent of the damage.
The Slavneft-Yanos refinery, which is jointly owned by Rosneft and Gazprom, has a crude processing capacity of 300,000 barrels per day, or 15 million metric tons per year. Ukraine claims the refinery supplies fuel and lubricants for the Russian military.
Russia’s Defense Ministry said it intercepted 856 Ukrainian drones across Russia and annexed Crimea between Monday night and Tuesday morning. More than half of those drones targeted Moscow and the surrounding regions, officials said.
In annexed Crimea, Kremlin-installed authorities said Ukrainian attacks on the regional power grid forced at least five cities on the Black Sea peninsula to introduce emergency power cuts.
Meanwhile, Russia continued its attacks on Ukrainian energy infrastructure, with Ukraine’s Energy Ministry reporting damage at facilities in 10 regions. Emergency outages were reported in Kyiv and six surrounding regions.
The Russian military confirmed it targeted four power plants overnight, as well as two substations and port infrastructure along the Danube River.
Ukraine’s largest private energy company, DTEK, said three thermal plants were forced to shut down following the Russian attacks.
