Ukraine has markedly stepped up its long-range attacks on Russian military industries and energy facilities in recent months, aiming to cut Moscow's revenue for its invasion — now in its fifth year — and make Russians feel the consequences.

According to Western analysts, it has also slowed Moscow's efforts on the battlefield, heaping pressure on the Kremlin to come to the negotiating table. "Our 'long-range sanctions' reached two oil refineries in Russia," Ukrainian President Volodymyr Zelenskyy wrote on the Telegram messaging app on Sunday. "Each (strike) means a reduction in the resources that fuel the Russian war machine, and another step toward peace." Debris from downed Ukrainian drones sparked a blaze at the refinery in Slavyansk-na-Kubani, a town in Russia's Krasnodar region, east of occupied Crimea, according to Gov. Veniamin Kondratyev. The falling debris killed one person in Slavyansk and wounded another in a nearby village, local authorities said. The Slavyansk site is one of southern Russia's major refineries, processing close to 4 million tons of crude per year, according to its operator's website. It is also a key source of petroleum products intended for export through Russia's Black Sea ports, including fuel oil, naphtha and marine fuel. Zelenskyy also claimed that a second Russian refinery, in the Yaroslavl region around 700 kilometers (435 miles) from the Ukrainian border, was hit during the nighttime strikes. There were no immediate reports from Russian authorities about the strike on the Yaroslavl refinery. Local Gov. Mikhail Evraev reported on Sunday morning that some roads between Moscow and the region's capital, Yaroslavl, were temporarily closed due to "an enemy attack by Ukrainian drones." Yaroslavl's airport also briefly closed overnight, along with others in southern and western Russia, according to the country's civil aviation agency.
