Russia escalated its attacks on Kyiv early Wednesday, launching waves of drones and missiles in its first combined aerial assault on the capital in more than 70 days, authorities said.

Russia attacked the Ukrainian capital Kyiv with a sophisticated combination of missiles and drones for the first time in 73 days on Wednesday, authorities said, as the Pentagon said most of the North Korean troops sent to help Moscow’s war effort are fighting to drive Ukraine’s army off Russian soil in the Kursk border region.
