Russia launched a wave of drones and missiles at Ukraine in an overnight attack on Monday, killing at least one person in Kyiv and hitting a metro station where hundreds of people were sheltering.

There were fires across the capital and at least six people were wounded. Kyiv’s mayor, Vitali Klitschko, said rescuers and medics were working on sites in four districts.

Smoke engulfed Lukianivska metro station, in an area that Moscow has repeatedly targeted. The Kremlin has dramatically stepped up its aerial bombardment of Ukrainian towns and cities in recent months, with Kyiv frequently bombed.

Video shows people standing on an underground platform filled with swirling dust. One woman can be heard sobbing.

Max, a 32-year-old resident, told the Guardian: “My friend ran to the underground. He called me during the night and said he heard the strike. Part of the building and even the roof tumbled down the escalator. There was smoke billowing on the platform.
