Russia fired missiles and drones into apartment buildings in Kiev for the second time in a week, killing at least 18 people on the eve of a crucial NATO summit, authorities said.
At least 18 people were killed in Kiev and the surrounding region, with around 60 wounded, according to officials on Monday.
Russia fired 68 missiles and 351 attack drones, Ukraine’s President Volodymyr Zelenskyy said.
Officials in the Kiev suburb of Vyshneve said they had evacuated residents because unexploded munitions could be in the debris.
Zelenskyy urged the alliance to take "strong decisions" on boosting Ukraine's air defences following the strike, which came just days after another Russian attack killed more than 30 people in Kiev.
The European Union also said that Ukraine needed air defence reinforcements.
The morning strike punched a crater into a multi-storey apartment block in the Ukrainian capital, ripping its top floors into two.
AFP reported more than 10 explosions during a ballistic missile alert during the night, with flashes in the sky as the blasts rang out.
It was the second attack in a week in which Russia deployed hard-to-intercept ballistic missiles, triggering Zelenskyy's desperate new appeal for allies to send missiles for the US-made Patriot air defence systems.
He is set to discuss the war with US President Donald Trump on the sidelines of the NATO summit in Ankara, which begins Tuesday.
"It is critically important that the world, first and foremost, the United States and our European partners, come out of the NATO summit in Ankara with strong decisions in support of our air defence, and thus the protection of ordinary people's lives," he said on social media.
‘Massive strike’
Russia's defence ministry said the "massive strike" using missiles and drones targeted what it described as "military-industrial enterprises," fuel and energy complex facilities in several Ukrainian regions.
Zelenskyy said Ukraine's army had shot down the Russian drones and cruise missiles but had an "insufficient supply of interceptor missiles" to stop the ballistic missiles.
European Commission president Ursula von der Leyen said the attack showed that Ukraine "urgently" needs more air defence and that this would be discussed at the NATO meeting.
Russia's army said its forces shot down more than 500 Ukrainian drones overnight.
Moscow's Mayor Sergei Sobyanin said on the state-backed Max messaging service that waves of the drones were bound for the Russian capital.
Kiev has increasingly targeted energy facilities inside Russia in an effort to weaken the Kremlin's war effort, triggering nationwide fuel shortages.
US-led attempts to broker an end to the more than four-year war have gone nowhere.
The White House said Trump would meet Zelenskyy on Wednesday during the NATO summit in a bid to invigorate diplomacy.
