Russia's largest air strike on Kyiv since spring killed two people early on Wednesday, with the debris of downed missiles falling on buildings, a park and a school, Ukrainian officials said.

Three others were hurt in the overnight strike on Ukraine's capital, and combat drones attacked infrastructure in the central region of Zhytomyr, where an unidentified facility and railway tracks were damaged and trains were delayed, they said.

"The blast wave broke all the windows, the entry doors are broken too. We were terribly scared," said Liudmyla Savchuk, a 57-year-old teacher whose apartment in northwestern Kyiv was damaged.

"Then there was another explosion in a couple of seconds, 20 or 30 seconds. We're cleaning everything now," she said, showing Reuters a piece of debris that had flown through a window.

Ukrainian air defences shot down all 28 incoming missiles and 15 of the 16 drones in the overnight attack, which also targeted the Black Sea region of Odesa, said General Valeriy Zaluzhnyi, Commander-in-Chief of Ukraine's armed forces.

Russia, which launched its full-scale invasion of Ukraine 18 months ago, did not immediately comment on the overnight air strike. Moscow said it had it foiled a Ukrainian drone attack on western Russia, shooting down unmanned aircraft over at least six regions and destroying a naval attack on Crimea.

 

"MASSIVE ATTACK"

The attack on Kyiv began with several groups of drones heading towards the city from different directions and was followed by a salvo of missiles launched by Tu-95 strategic bombers, he said.

It was not immediately clear what had been hit by the single drone that was not shot down.

"Kyiv has not experienced such a powerful attack since spring. The enemy launched a massive, combined attack using drones and missiles," Serhiy Popko, the head of the city's military administration said on the Telegram messaging app.

"All in all, the air defence forces destroyed more than 20 enemy targets."

The bodies of two people were found in a non-residential building, mayor Vitali Klitschko said on Telegram.

At around 4.00 a.m. (0100 GMT), a burning lump of missile debris flew through the night sky over southwestern Kyiv's outskirts and landed nearby, a Reuters witness said.

Several buildings were damaged by debris, and officials in the Kyiv region said six private houses were damaged by missile fragments and several people were injured.

"Humans don't do such things. There are no military objects here, nothing – just an apartment block... The missiles fell in the park," said Roman Feshchenko, 76, a resident in the northwest of Kyiv, one of four places where debris came down.

The general prosecutor's office said separately that an 82-year-old woman had been killed overnight by Russian shelling in her home in the village of Svarkove in the northern region of Sumy. (Additional reporting by Pavel Polityuk; Writing by Tom Balmforth; Editing by Timothy Heritage)
