Russian forces struck the Ukrainian capital with ballistic missiles on Tuesday, hitting a nine-storey residential building and a critical thermal power plant in the second attack in 24 hours. Kyiv Mayor Vitali Klitschko said two people were killed and 21 injured, with 16 hospitalised including four in serious condition.
"Once again, no advance warning. The main target was energy infrastructure, specifically thermal plant No. 4," Mr Zelenskyy said in a post on Telegram. He said it was unfair that Kyiv was enduring attacks without warnings from partners, especially as Ukrainian intelligence indicated the Russians were preparing further ballistic missile launches.
The President said the strikes showed Moscow does not consider itself bound to abide by what US President Donald Trump announced over the weekend as an energy ceasefire, an agreement that neither Moscow nor Kyiv has confirmed.
Ukraine relies heavily on US intelligence for early warnings of missile strikes. Mr Trump said Washington was still sharing intelligence, even as he pressured Kyiv to halt attacks on Russian refineries. Reuters and other media have reported that US officials have threatened to cut off intelligence sharing and weapons sales to Ukraine unless it stops striking Russian refineries.
Ukrainian authorities confirmed on Wednesday morning that the overnight attacks, which primarily targeted Kyiv and Kharkiv, damaged 30 energy facilities. Mr Zelenskyy said at least 600,000 people were left without power.
