Ukrainian officials said the country's capital, Kyiv, was struck by a Russian airstrike overnight that killed four people. Authorities described the assault as coming after an earlier air raid had completed and the second strike started Tuesday at 06:00 local time, which is 04:00 GMT, warning of the approaching threat of ballistic missiles and asking for people to find shelter immediately.
The strike hit the central Shevchenkivskyi district, blowing out windows - including in a metro station - and a fire in a non-residential building. The mayor of the city, Vitali Klitschko, acknowledged the destruction, but was unable to confirm what the exact targets were. Online footage shows a car up in flames and water flowing down a flooded street.
Klitschko said air defenses were active around the Ukrainian capital during the attack.
It is the second lethal attack on Kyiv this month after a New Year's Day strike that killed two people.
In the southern city of Zaporizhzhia, local authorities said six people were injured in a Russian strike on Saturday. One woman is in critical condition.
These airstrikes form part of the ongoing conflict that began with the large-scale invasion of Ukraine by Russia in February 2022. The strikes come after a series of attacks by Ukraine on Russian territory earlier in the week.
On Tuesday, Ukrainian military struck ammunition depots and chemical plants, among other facilities far from the border, across regions in Russia - some hundreds of kilometres away. According to the General Staff of Ukraine's Armed Forces, such strikes significantly reduce the military potential of the invaders.
It was a "painful blow" to Russia's capabilities of maintaining its war-sustaining logistics, according to officials at Ukraine's SBU intelligence agency. In turn, Russia said it had downed US-supplied long-range Atacms missiles and UK-made Storm Shadow cruise missiles and vowed to retaliate against the attacks.
And with that, questions about the long-term trajectory and resolution of the war remain, with some analysts indicating it could last well into 2025.
