Russia's overnight attacks killed one person in Ukraine's northeastern region of Kharkiv and injured several more in the northern city of Chernihiv, regional Ukrainian officials said on Tuesday.

A surprise Ukrainian drone attack that targeted Russian air bases hosting nuclear-capable strategic bombers was unprecedented in its scope and sophistication.
