Kyiv Mayor Vitaliy Klychko, who visited the damaged building, said 18 apartments had been destroyed. He also said the attack had disrupted the city’s water supply.
More than 1,500 rescuers and police officers are working in the aftermath of Russia’s overnight attacks, almost 600 of them in Kyiv, Minister of Internal Affairs Ihor Klymenko said.
Dozens of people have been recovered from the damaged building and more than 10 people are thought to be missing, he said in a statement, with canine units involved in the search.
Teams say they have moved more than 20 cubic metres of debris and evacuated five damaged vehicles.
The strikes also damaged other residential buildings, a school, a veterinary clinic and other infrastructure in Kyiv, according to Zelensky.
The large-scale attack saw Russian drones fly across much of Ukraine, with the regions of Kremenchuk, Bila Tserkva, Kharkiv, Sumy, and Odesa also coming under fire, Prime Minister Svyrydenko said.
“Ukraine needs help in strengthening its air defense,” she wrote on social media. “This is the only way to save our people and our cities.”
Ukraine’s Foreign Minister Andriy Sybiha condemned Russian President Vladimir Putin for the “barbaric attack”, which he said showed Moscow was pursuing “aggression and terror” over peace.
He noted the attack had taken place during a crucial summit between US President Donald Trump and China’s Xi Jinping, and urged the two leaders to exert pressure on Russia.
“I am certain that the leaders of the United States and China have enough leverage over Moscow to tell Putin to finally end the war,” he said.
