Residents of the Ukrainian capital Kyiv were urged to head to air raid shelters early on Friday as sirens wailed across the city, a day after Russia carried out one of the biggest aerial assaults since it started the war in February.
Shortly after 2.00 a.m. Kyiv's city government issued an alert on its Telegram messaging app channel about the air raid sirens and called on residents to proceed to shelters.
Olekskiy Kuleba, governor of Kyiv region, said on Telegram that an "attack by drones" was underway.
