Kyiv Under Fire: Russia launched one of the heaviest barrages of the war, hitting Kyiv and nearby areas with hundreds of drones and missiles, including the nuclear-capable hypersonic Oreshnik, killing 4 and wounding more than 80; officials say dozens of homes and schools were damaged, with fires and debris clearing continuing into Sunday. Nuclear Escalation Row: Ukraine says the Oreshnik was used for only the third time since the full-scale invasion, and Zelenskyy called for “consequences” and fresh air-defense action as European leaders condemned the strike as reckless nuclear brinkmanship. Retaliation Cycle: Moscow framed the attack as revenge for a Ukrainian strike in Russian-controlled territory that killed 21 in a dormitory, while Ukraine pressed for emergency UN Security Council and OSCE meetings. Broader War Spread: Separate reports logged drone strikes in Kharkiv and a bomb attack in Druzhkivka that killed a woman and wounded five. Russia-UK Tension: In a parallel development, reporting says Russia jammed the RAF plane carrying UK Defence Secretary John Healey, disrupting GPS during flight.
