Four people have been killed in a Russian air strike on Kyiv overnight, local officials say.
The city’s mayor, Vitali Klitschko, said air defences were in operation around the Ukrainian capital.
Windows were shattered in Shevchenkivskyi district, including at a metro station, and a fire broke out in a non-residential building, he added. It is not clear what was targeted.
Authorities warned of a ballistic missile threat and urged locals to head for shelter.
Videos posted online showed a car in flames and water rushing down a flooded street.
It is the second fatal attack on Kyiv this month, following a deadly strike on the city on New Year’s Day.
Meanwhile, in the southern city of Zaporizhzhia, the local authorities say six people were wounded in a Russian strike on Saturday. One woman is said to be in a serious condition.
These strikes are the latest in the war that began following Russia’s full-scale invasion of Ukraine in February 2022.
They follow several Ukrainian attacks on Russian territory earlier in the week.
On Tuesday, ammunition depots and chemical plants were hit across multiple regions of Russia, some of which were hundreds of kilometres from the border, according to the General Staff of Ukraine’s Armed Forces.
Sources in Ukraine’s SBU intelligence agency told the BBC the attack on Tuesday had been a “painful blow” to Russia’s ability to wage war.
At the time, Russia said it had shot down US-supplied long-range Atacms missiles as well as UK-made Storm Shadow cruise missiles, and vowed to respond to the attack.
