Ukrainian Drones Strike Ilsky Oil Refinery in Krasnodar, Russia — Energy Campaign Continues on Day 1,559

On June 2, 2026 (Day 1,559), Ukrainian long-range drones struck the Ilsky oil refinery in Krasnodar Krai, southern Russia, igniting a fire at the facility. The Ilsky refinery, located approximately 700–750 km from Ukraine's eastern border, is one of Russia's strategically important southern refining sites. The strike is part of Ukraine's sustained drone campaign against Russian energy infrastructure throughout 2026: Ukrainian forces had already struck 15 Russian oil refineries in January–May 2026, knocking out approximately 40% of Russia's main oil refining capacity. The Ilsky strike extends the campaign further south, targeting Krasnodar's energy sector. Separately, a Ukrainian drone struck a residential home in Russia's Belgorod region, injuring an 11-year-old boy. The dual strikes demonstrate Ukraine's continued ability to conduct deep-precision operations against Russian territory despite one of the largest retaliatory Russian attacks of the war overnight.
