Heavy overnight Russian strikes killed at least six people in Ukraine and cut power to large parts of the capital Kyiv, authorities said on Wednesday.
Strikes hit multiple regions after President Volodymyr Zelenskyy said Ukraine had received no advance warning from Western allies before a Russian strike on a Kyiv power plant.
Ukraine depends heavily on Western intelligence to detect incoming Russian attacks and pick its own targets, but renewed strain with U.S. President Donald Trump has cast doubt on those arrangements.
In Kyiv, a Russian strike on a multi-story building in Desnianskyi district killed two people, while another attack in Golosiivsky claimed one life, Ukraine’s state emergency service said.
Ukrainian military authorities also reported two deaths and six injuries in Russian attacks on the Dnipropetrovsk region. Another person died in southeastern Zaporizhzhia.
Agence France-Presse (AFP) reporters in Kyiv heard a series of explosions overnight and said eastern parts of the city lost water and electricity.
"Energy facilities in Kyiv and the surrounding region have come under a massive ballistic missile strike. There are power disruptions in the capital," Mayor Vitali Klitschko wrote on Telegram, urging people to remain in shelters.
DTEK, Ukraine’s largest private energy provider, said on Telegram that the attack forced emergency power cuts in the Darnytskyi, Dniprovskyi, Pecherskyi, and Solomianskyi districts, and in part of Golosiivskyi.
Russian ballistic missiles also hit Kharkiv and Zhytomyr regions, while other attacks targeted Sumy and Chernigiv.
Russia’s Saratov governor said, citing preliminary figures, that a Ukrainian aerial attack killed 1 person in the city of Balakovo.
Moscow Mayor Sergey Sobyanin said air defense units shot down nearly 500 drones heading for the capital overnight, while officials reported about 160 more intercepted over Rostov and others aimed at the city.
Earlier, Zelenskyy said a Russian strike on a Kyiv power facility on Tuesday evening came without any advance warning from Western allies.
"A Russian ballistic missile attack on Kyiv. Once again, no early warning from our partners," he wrote on Facebook. "The main target was energy infrastructure, specifically the CHP-4. Unfortunately, it was hit," he continued.
Zelenskyy said Ukrainian systems detected the missiles only when they approached the city.
"This is absolutely unjust: when they are destroying our infrastructure, and Ukraine is not even receiving early warnings about ballistic missile launches," he added.
Kyiv, home to some 3 million people, has faced growing attacks from Russian drones and missiles, with energy infrastructure a key target.
Overnight from Monday to Tuesday, Kyiv residents heard explosions from Russian strikes before air raid sirens sounded, something that has occurred only rarely in the past.
Ukrainian officials attributed the problem to the Russian military’s use of hard-to-detect missiles or possible technical issues.
Trump announced an “energy ceasefire” on Truth Social on Sunday, saying Russia and Ukraine had agreed to halt their punishing long-range strikes on power infrastructure.
Zelenskyy expressed surprise at the news and said subsequent strikes on Ukraine’s energy infrastructure were Russian President Vladimir Putin’s “answer” to Trump’s claim.
Trump has repeatedly criticized Zelenskyy over strikes on Russian oil refineries and on Saturday suggested it was “time for Ukraine to get a new president."
The U.S. leader has drawn criticism from Zelenskyy and a political backlash at home after announcing plans last week to buy diesel from Russia despite wartime sanctions on Moscow.
