“Several enemy UAV (unmanned aerial vehicles) are over and near the capital,” Kyiv mayor Vitali Klitschko said on Telegram, urging people to take cover. Witnesses heard numerous blasts in Kyiv in what sounded like air defence systems in operation and saw objects being hit in the air.

Russia launched several waves of drones targeting Kyiv early on Monday, with air defence units successfully defending the city, Ukraine's military said.
