Ukraine Launches 347-Drone Mass Attack Across 20 Russian Regions — Second-Largest Drone Barrage of the War, Shutting Down Moscow Airports

Overnight on May 6-7, 2026, Ukraine launched its second-largest aerial drone attack of the war, with Russia's Defense Ministry reporting 347 Ukrainian drones intercepted across 20 Russian regions including Moscow Oblast. The attack disrupted air traffic at all three major Moscow airports — Sheremetyevo, Domodedovo, and Vnukovo — with nearly 100 flights delayed or canceled by midday on May 7. Ukraine framed the attack as a direct, symmetrical response to Russia's rejection of Ukraine's open-ended ceasefire and continued strikes on Ukrainian civilians (27 killed May 5). President Zelensky confirmed the operation, stating: 'Russia rejected the ceasefire. Russia continues to hit Ukrainian cities. Ukraine will act symmetrically.' Russia's MoD reported its air defense systems destroyed 347 drones in the overnight operation, though Ukrainian sources reported damage to Russian military and infrastructure targets. The attack was the largest on Russia since Ukraine's record 389-drone barrage in March 2026. The scale of the Ukrainian drone campaign has consistently forced Russia to allocate substantial air defense resources to protecting its interior, diverting them from front-line use.
