Ukrainian forces struck the Gazprom Neftekhim Salavat oil refining and petrochemical complex in Russia's republic of Bashkortostan (a region roughly 1,300 kilometres southeast of Moscow), igniting a fire at one of Russia's largest refineries, which processes up to 74 million barrels of oil annually. The attack was the fourth such strike in three days as part of Kyiv's campaign to cripple Russia's oil sector, with a separate refinery in Orsk having already suspended operations for up to six months due to damage from an earlier drone strike. Ukrainian officials say the campaign is intended to pressure President Vladimir Putin into seeking a peace deal, though there is no sign the strategy is yet bearing results.
