Russia launched a massive overnight missile and drone attack on Kiev early Sunday, hitting residential areas, a school and commercial buildings in the Ukrainian capital, as Moscow vowed to retaliate for Ukrainian attacks on the Russian-held territory that it said killed 18 people. The barrage injured at least 10 people, sparked fires in several districts and forced residents into underground shelters as air raid sirens echoed across the city for hours.The attack, which Ukrainian officials described as a “mass ballistic missile attack”, continued Sunday morning and officials warned that additional missiles and drones were still approaching the capital.“The capital has been hit by a massive ballistic missile attack,” Timur Tkachenko, head of the Kiev city military administration, wrote on Telegram. “There are currently reports of at least 4 locations affected by the attack: Shevchenkivsky, Dniprovsky and Podilsky districts. There are preliminary reports of fires and damage to residential buildings.”“Strike drone attacks continue; ballistic missile threat still persists. Stay in shelters!” He added.According to Associated Press journalists on the ground, powerful explosions were heard throughout central Kiev overnight, including near government offices. The impact of the attacks shook buildings and thick smoke spread over many parts of the city.Kyiv Mayor Vitaliy Klitschko said a school building in the Shevchenkivskyi district was damaged, while civilians were sheltering inside. “A school has been damaged in the Shevchenkivsky district,” Klitschko posted on Telegram. He told that there is a fire.Emergency crews were also dispatched to Kyiv’s Podilsky district after debris fell in a non-residential area, while a fire broke out near residential buildings in the Shevchenkivskyi district, damaging windows and surrounding structures.Officials said damage was reported in at least nine districts of the capital, with supermarkets, warehouses and residential complexes also affected. Regional governor Mykola Kalashnik said several communities in the wider Kyiv region also suffered damage.The attacks came after Russia warned of retaliation for recent Ukrainian attacks in Russian-occupied eastern Ukraine. Moscow had earlier accused Kiev of carrying out an attack on a college dormitory that reportedly killed 18 people.Before the attack, Ukrainian President Volodymyr Zelensky, citing intelligence shared by the United States and Western allies, warned that Russia could launch a major air strike involving the Oroshnik hypersonic ballistic missile. Ukraine’s air force later issued a warning about a possible Orashnik launch, though it was not immediately clear whether the missile was used in Sunday’s attack.Russia first deployed the Oreshnik missile against the Ukrainian city of Dnipro in November 2024 and used it again in the western Lviv region earlier this year.Russian President Vladimir Putin has claimed that the nuclear-capable missile travels at a speed of Mach 10 and can penetrate underground bunkers several floors deep. Describing the weapon as traveling “like a meteorite”, Putin has also said that the missile is immune to existing air defense systems and that many conventional attacks using the weapon could match the devastation caused by a nuclear attack.
