Russian Drone Strikes Multi-Story Residential Building in Kharkiv — Two Districts Targeted — Day 1,561

On June 4, 2026 — Day 1,561 of Russia's full-scale invasion — Russian forces launched drone strikes on two districts of Kharkiv, Ukraine's second-largest city. One drone struck a multi-story residential building, causing a fire. Ukrainian emergency services responded to the blaze; casualties were not immediately confirmed in early reports. The strikes on June 4 continued a pattern of near-daily Russian drone and bomb attacks on Kharkiv, which has been under Russian aerial assault throughout the war due to its proximity (approximately 40 km) to the Russian border and its significance as Ukraine's industrial and cultural capital in the northeast. Separately, ISW confirmed that neither Russian nor Ukrainian forces made confirmed territorial advances anywhere along the frontline on June 4, with the Pokrovsk, Huliaipole, Lyman, and Kupiansk sectors all recording combat engagements but no net movement.
