Ukraine launched a large attack with at least 361 drones targeting Russia overnight, sparking a brief fire at the vast Kirishi oil refinery in Russia's northwest, Russian officials said on Sunday, reporting no injuries.
As world powers talk about how to end the deadliest conflict in Europe since World War Two the drone war has escalated, with Russian drones downed in NATO-member Poland and attacks by Ukraine against oil refineries and pipelines in Russia, the world's second biggest oil exporter.
Russia's defence ministry said at least 361 drones had been shot down by Russian air defence systems, including four guided aerial bombs and a U.S.-made HIMARS missile. It did not give details about the location of the attacks.
Alexander Drozdenko, the governor of the Leningrad region, said three drones were destroyed in the Kirishi area and a fire sparked by falling debris had been put out. He said no one was injured.
Ukraine's drone command confirmed it attacked the refinery and said it had "carried out a successful strike."
Reuters was unable to immediately verify the scale of the damage, if any, to the refinery.
Ukrainian President Volodymyr Zelenskiy, speaking in his nightly video address, praised Kyiv's military and special services for the string of long-range attacks on Russian oil installations.
"The most effective sanctions – the sanctions that work the fastest – are firing on Russian oil plants, on their terminals, on their oil depots," Zelenskiy said. "They have significantly restricted the Russian oil industry, and this significantly limits the war."
Zelenskiy singled out an attack last week on Russia's northwestern port of Primorsk for the first time which he said had inflicted "significant damage. This has been checked."
Kirishi refines about 17.7 million metric tons per year (355,000 barrels per day) of Russian crude, or 6.4% of the country's total.
PRESSURE TO TIGHTEN ENERGY SANCTIONS
In recent weeks, the United States has stepped up pressure on NATO countries to tighten energy sanctions on Russia in a bid to curtail its revenues and help end the war with Ukraine, a conflict U.S. President Donald Trump has struggled to bring to a close.
Trump said on Saturday the U.S. is prepared to impose fresh energy sanctions on Russia, but only if all NATO nations cease purchasing Russian oil and implement similar measures.
Russia said on Sunday it had fired a Zircon (Tsirkon) hypersonic cruise missile at a target in the Barents Sea and that Sukhoi Su-34 supersonic fighter-bombers had carried out strikes as part of joint military exercises with Belarus.
An oil company in Russia's Bashkortostan region will maintain production levels despite a drone attack on Saturday, regional governor Radiy Khabirov said.
