Russian forces launched a major drone and missile attack on Kyiv overnight, killing 18 people.
The city's mayor described it as the "most massive attack" on the Ukrainian capital.
Several neighbourhoods were evacuated as strikes rocked buildings throughout the city, hours after Ukrainian President Volodymyr Zelensky warned Russia was preparing an attack.
The BBC's Southern and Eastern Europe correspondent, Sarah Rainsford, reports from a nine-storey block of flats in Kyiv that was completely destroyed in the attack.
