KYIV, Ukraine (AP) — Russia pounded Ukraine’s capital with another major missile and drone attack overnight into Thursday, killing at least two people and causing fires across Kyiv a day after the heaviest drone attack so far in the more than three-year war, Ukrainian officials said.

Russian forces have become adept at retooling Iranian kamikaze Shahed drones, making them more deadly and less vulnerable to Ukrainian defenses, according to Kyiv.
