Russia Launches Massive Overnight Strike — 73 Missiles (8 Zircon) + 656 Shaheds; Kyiv Residential Building Collapses; 17+ Killed Nationwide — Day 1,559

Overnight June 1–2, 2026 — Day 1,559 of Russia's full-scale invasion — Russia launched one of the largest combined missile and drone strikes of the war: 73 missiles including 8 Zircon hypersonic missiles (the largest single-use of Zircon in the entire war) combined with 656 Shahed-type attack drones. Ukraine's air defenses intercepted 40 missiles and 602 drones. At least 17–18 people were killed and more than 100 wounded nationwide. In Kyiv, 6 were killed and 63–65 wounded; a 9-story residential building in the Podilskyi district partially collapsed, with people feared trapped in rubble. Fires broke out across 7 city districts; citywide power outages were recorded. In Dnipro, at least 4 people were killed and 16 wounded. In Kharkiv, 10 were wounded including a child — the city sustained hits from 15 drones and 2 missiles. In Zaporizhzhia, 6 missiles were directed at the region. Russia's MoD claimed to have targeted 'military-industrial, fuel, transport facilities and military bases' in Kyiv, Zaporizhzhia, Kharkiv, Dnipro, Poltava, Khmelnytskyi, and Sumy regions. This is the largest attack since Russia's May 23, 2026 strike (600 drones + 90 missiles), and comes the day after IAEA Update 307 confirmed a drone strike on the Zaporizhzhia NPP turbine hall. The attack is part of Russia's sustained aerial escalation throughout May–June 2026, designed to overwhelm Ukraine's depleted interceptor stockpiles and break civilian morale.
