Ukrainian long-range drones have carried out a second attack on one of Russia's largest oil refineries in the Volgograd region, as reported by a senior Kyiv official. This latest strike comes amidst Ukraine's efforts to impede the Russian army's advance along certain parts of the front line, with the third anniversary of the conflict looming.
The refinery in the Volgograd region, which is among Russia's top 10 refining facilities and processes nearly 6% of the country's oil, was hit late Sunday. Russian authorities confirmed a brief fire at the refinery during the drone attack.
