At least three explosions have been heard in the Ukrainian capital Kyiv, after air raid sirens went off.
Mayor Vitalii Klitschko said residential buildings in the central Shevchenkivskiy area had been damaged.
Andriy Yermak, head of President Zelensky’s office, said the attacks were from so-called kamikaze drones.
A week ago, the capital was hit by several Russian missiles at rush hour, part of nationwide attacks which left 19 dead.
The explosions on Monday happened at around 07:00 local time (04:00 GMT), said the BBC’s Paul Adams, who is in the city.
Writing on the Telegram social media site, Mr. Klitschko said they were in the Shevchenkivskiy district, which was hit by several strikes last week.
He said rescuers were on site, and told residents to stay in air raid shelters.
