Russia's Defence Ministry confirmed that its forces had carried out a "massive" strike against communications and energy infrastructure in Ukraine, the Interfax news agency reported. It said Russian forces hit two plants supplying power and heating in Kyiv, two other plants in the wider region and an electricity substation.
Other targets included a heating and power plant in Kharkiv, Ukraine's second-largest city, and a thermal power facility that the ministry said supplied the Ukrainian military in the southeast of the Kharkiv region. Moscow also said it struck a data centre in Kyiv that it claimed was used to gather intelligence on Russia's military.
Kyiv Mayor Vitali Klitschko urged residents to remain in shelters. "Energy facilities in Kyiv and the surrounding region have come under a massive ballistic missile strike. There are power disruptions in the capital," he wrote on Telegram. DTEK, Ukraine's largest private energy provider, said the attack caused emergency power cuts in several urban districts of Kyiv.
A strike on a multistorey building in the capital's Desnianskyi district killed two people, while another in the Golosiivskyi district killed one, Ukraine's state emergency service said. The Ukrainian military reported two killed and six wounded in the Dnipropetrovsk region, and another death in the Zaporizhzhia region. Further missile attacks were reported in the Kharkiv, Zhytomyr, Sumy and Chernihiv regions.
Al Jazeera's Audrey MacAlpine, reporting from Kyiv, said a record number of hypersonic missiles were used and that more than half a million people in Ukraine were without power.
President Volodymyr Zelenskyy said Ukraine received no early warning from its Western partners of the attack, raising questions about intelligence sharing. "A Russian ballistic missile attack on Kyiv. Once again, no early warning," he wrote on Facebook. "This is absolutely unjust: when they are destroying our infrastructure, and Ukraine is not even receiving early warnings about ballistic missile launches." He said the missiles were detected only as they neared Kyiv.
Zelenskyy also accused Russia of violating the "energy ceasefire" that Trump announced on Sunday, calling the strike on energy infrastructure deliberate and demonstrative in scale.
