The attacks come days after Trump says Putin had "very strongly" promised response to Ukraine "Spider web" attack.

The air assault killed at least three people. Kharkiv’s mayor described it as “the most powerful attack” since the beginning of the war.

Sharing further details of the large-scale assault, Ukrainian officials said that cruise missiles and hundreds of drones were launched targeting Kyiv, Chernihiv, Lutsk and Ternopil.
