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.

It comes a week after the capital was hit by several Russian missiles at rush hour, in a nationwide attack 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.
