Three people have died and at least 26 others injured in a wave of Russian drone and missile strikes on Kyiv, Ukrainian officials say.

Mayor Vitaliy Klitschko described strikes, which caused explosions and fires in residential buildings across the city, as massive.

Kyiv's energy infrastructure was also damaged, leaving some buildings in the north-east without heat, he said. Ukraine's air force reported several other regions across the country were also being targeted.

Russia's defence ministry stated that it had downed or intercepted 216 Ukrainian drones that had aimed at its industrial facilities and disrupted air travel, according to Reuters.

In Kyiv, residential buildings came under attack in practically every district, the head of the city's military administration, Tymur Tkachenko, reported on Telegram.

He issued a warning to take shelter just after midnight local time, noting that it's loud in Kyiv.

Falling debris and fires have damaged multiple high-rise apartment buildings, a hospital, school, and administrative buildings, according to emergency services.

More than 40 people have been rescued, including 14 from a fire in a residential building in the Desnayanskyi district where one person died.

Another person was pulled from beneath rubble, and medical teams were deployed to all fires. Klitschko reported that nine people are in the hospital, with one man in an extremely serious condition.

Parts of the city's heating network were also compromised in the attacks, raising concerns about electricity and water supplies being disrupted.

The overnight strikes follow the deaths of six people in another Russian offensive earlier in the week that also damaged residential buildings and energy infrastructure.

Russia claims its strikes on energy targets are meant to affect the Ukrainian military.

These actions prompted Ukrainian President Volodymyr Zelensky to call for a tightening of Western sanctions on Russian energy, shortly after the US granted Hungary an exemption.

US President Trump initially announced sanctions on Russian oil following stagnant ceasefire talks with President Putin.
