The Mayor of Kyiv, Vitali Klitschko, tells the BBC Ukraine needs more help from its partners to protect civilians
At least 15 people have been killed in the latest Russian strikes targeting the Ukrainian capital, Kyiv's mayor said, as Ukraine continues to face a shortage of air defence missiles.
Blocks of flats and warehouses were struck across the city overnight, the State Emergency Service of Ukraine said, while a children's hospital and 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 the supplies and President Volodymyr Zelensky said that "as long as Ukraine does not have enough anti-ballistics, Russia will not seriously think about peace".
Cars were left burning in Kyiv after the strikes
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 implied that none of the Russian ballistic missiles used overnight were intercepted.
Ukraine has relied on American supplies of Patriot interceptor missiles to combat Russian ballistic missiles, but the US has used much of its stockpile during the war with Iran.
The Russian defence ministry said it 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 is to be observed on Friday.
At a local school in the Solomyanski disctrict, the windows were knocked out and its 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 house supplying heating to the surrounding apartment blocks.
