At least 15 people have been killed in the latest Russian strikes on the Ukrainian capital, Kyiv's mayor said, as Ukraine continues to face shortages of air defence missiles.
Blocks of flats and warehouses were struck across the city overnight, according to Ukraine's State Emergency Service. A children's hospital and a school were also damaged.
Speaking to BBC News at a wrecked apartment block in Kyiv, Mayor Vitali Klitschko said Ukraine needed "ammunition, anti-missile systems - we need support from our partners".
Kyiv relies on Western allies for air defence supplies. President Volodymyr Zelensky said that "as long as Ukraine does not have enough anti-ballistics, Russia will not seriously think about peace".
He added: "The interceptors for the Patriots have not yet been replaced, and they are needed every day. Each additional missile saves the lives of our people."
An update released by the Ukrainian Air Force on Thursday morning indicated that none of the Russian ballistic missiles used overnight had been intercepted.
Ukraine has relied on US-supplied Patriot interceptor missiles to counter Russian ballistic missiles, but the US has used much of its stockpile during the war with Iran.
The Russian Defence Ministry said it had used air-, land- and sea-based weapons to target military facilities and warehouses.
The latest strikes on Kyiv began around midnight local time, as air raid sirens sounded across the city, followed by the impact of Russian missiles.
The strikes cut power to thousands of properties, plunging parts of the Kyiv region into darkness. A day of mourning will be observed on Friday.
At a local school in the Solomianskyi district, windows were blown out and playing fields were left covered in debris.
A nearby storeroom was destroyed, exposing the basement. The BBC was told it was a laundry and boiler room supplying heating to surrounding apartment blocks.
Ukraine's deputy intelligence chief told the BBC that the attack was the kind of operation Russia was planning ahead of winter in an effort to make life more difficult for civilians.
Anastasiia Kovtun's flat was in a nine-storey building hit in the attack.
The primary school teacher said she felt as though her "head was going to blow" when she heard explosions in her area while sheltering.
"It's so frightening to realise it's your house, you never think you're going to be next," she told the BBC.
Valeria Bondaruk moved to Kyiv after her home in southern Ukraine was bombed, believing the capital would be safer for her and her daughter.
Now she has been forced from her home for the second time during the war.
She told the BBC she feared for her 13-year-old daughter's future and was considering leaving Ukraine.
