A Ukrainian drone strike on Saturday, January 10, 2026, ignited a fire at an oil depot in Russia's southern Volgograd region, as confirmed by local authorities and Ukraine's General Staff. The strike, which Ukraine's military claimed targeted the Zhutovskaya oil depot to disrupt fuel supplies to Russian forces, prompted consideration of resident evacuations near the facility. This incident marks another instance of Ukraine's strategy to conduct long-range drone strikes on Russian energy infrastructure, aiming to reduce Moscow's oil export revenues that fund its ongoing invasion. The drone attack occurred amidst a significant intensification of hostilities, with Russia launching a massive overnight assault on Ukraine. Ukrainian officials reported hundreds of drones and dozens of missiles fired by Moscow overnight into Friday, January 9, 2026, resulting in at least four fatalities in Kyiv and widespread power and heating disruptions. During this intensified barrage, Russia also employed its powerful, nuclear-capable Oreshnik hypersonic missile, striking western Ukraine. This marks only the second recorded use of this advanced missile in the nearly four-year conflict, serving as a clear warning to Kyiv's NATO allies. Russia's Defence Ministry confirmed its forces used aviation, drones, missiles, and artillery to target Ukrainian energy facilities and fuel-storage depots, without specifying locations or damage. Both sides continue to deliberately target each other's energy infrastructure as a key tactic in the war, with Russia aiming to cripple Ukraine's power grid and 'weaponize winter'.
