Russia attacked several Ukrainian regions with Russian ballistic missiles and drones early on Friday, officials said, with Kyiv mayor Vitali Klitschko saying four people were killed and 20 injured in the capital. Multiple explosions were heard in the city and falling debris triggered fires across several districts as air defence systems tried to intercept incoming targets, said the Kyiv city administration’s head, Tymur Tkachenko. Authorities reported damage in several districts and rescue workers were responding at multiple locations. Officials urged residents to seek shelter.

A fire broke out in a 16-story residential building in Kyiv’s Solomyanskyi district and emergency services evacuated three people from the apartment. Rescue operations were continuing. Another fire broke out in a metal warehouse. Tymchenko said the metro tracks between two stations in Kyiv were damaged in the attack but no fire or injuries occurred.

A Shahed drone exploded near an apartment building in northern Ukraine’s Chernihiv region, shattering windows and doors, the regional military administration chief said. Explosions from ballistic missiles were also recorded on the city’s outskirts, Dmytro Bryzhynskyi added.
