AFP journalists in the capital heard air raid sirens wailing out over the city before several hours of thunderous explosions and flashes in the sky sent Kyiv residents running to shelter in metro stations.
The Ukrainian air force said Russia had launched 675 attack drones and 56 missiles, mainly at Kyiv, adding its air defence units had downed 652 of the drones and 41 missiles.
“Everything was burning. People were screaming… people were shouting,” Andriy, a Kyiv resident still wearing a nightgown and with blood stains on his shirt, told AFP near a collapsed Soviet-era residential building.
President Volodymyr Zelensky said 20 sites in the capital were damaged including homes, a school, a vet clinic and other civilian infrastructure.
Seven bodies were pulled from the rubble of a single destroyed residential building — three men, three women, and a young girl, police said.
Another 45 were wounded.
Russian attacks also wounded people in the southern regions of Odesa and Kherson, and in the eastern region of Kharkiv.
“These are definitely not the actions of those who believe the war is coming to an end. It is important that partners do not remain silent about this strike,” Zelensky said.
Ukraine said it shot down 94% of all drones and 73% of the missiles fired by Russia.
“The most difficult challenge is defending against ballistic missiles,” he said.
A slew of Ukraine’s allies, including the United Kingdom, Estonia, Latvia, Finland, the Netherlands, Moldova, and Slovakia condemned the fatal attacks.
“By bombing civilians, Russia demonstrates less its strength than its weakness: it is running out of solutions on the military front and does not know how to end its war of aggression,” French President Emmanuel Macron said.
EU chief Ursula von der Leyen says Kyiv attacks show that Russia “openly mocks” efforts to end the war.
Russia, which invaded Ukraine more than four years ago, said the wave of missiles and drones had targeted military-linked sites and energy facilities that support the Ukrainian army.
At daybreak, AFP journalists witnessed chaotic scenes as rescue workers dug through mounds of debris from a collapsed residential building gutted in the attack.
Emergency service workers were seen hauling from the site those wounded and killed in the strikes, and residents cried as they waited for news of loved ones and neighbours.
The barrage is the latest setback for efforts to end the conflict after US President Donald Trump raised faint hopes for peace by brokering a three-day ceasefire between Kyiv and Moscow last week, and Russia’s leader Vladimir Putin suggested the war could be winding down.
But the brief truce was marred by allegations of violations and both sides resumed attacks straight after.
Russia’s army fired more than 1,500 drones at Ukraine over Wednesday and Thursday, Kyiv’s air force said.
The Kremlin has poured cold water on the idea that vague comments from Putin on Saturday that the war was “heading to an end” meant Moscow would soften its position.
On Wednesday it repeated its demand that Ukraine fully withdraw from the eastern Donbas region before a ceasefire and full-scale peace talks can take place.
Kyiv has rejected such a move as tantamount to capitulation.
Kyiv has urged Trump to discuss ending the conflict during his meetings in Beijing this week with Chinese leader Xi Jinping.
“This barbaric attack during such an important summit shows that the Russian regime poses a global threat to international security. Instead of peace and development, Moscow pursues aggression and terror,” Ukraine’s Foreign Minister Andriy Sybiga said.
Russia drones on Thursday also struck a UN vehicle in the southern Ukrainian city of Kherson, Zelensky said, accusing Moscow of having deliberately targeted it, but adding there were no casualties.
Russia’s invasion of Ukraine in February 2022 has spurred the worst conflict in Europe since World War II, killing hundreds of thousands of people and displacing millions more.
