The U.S. says there will be a "firm response" as Ukrainian forces holding ground in Russia's Kursk region now face North Korean troops "engaging in combat."

Nov 10 (Reuters) - Ukraine launched at least 17 drones targeting Moscow early on Sunday, forcing the temporarily closure of two of the capital's airports, Russian officials said.

Ukraine attacked Moscow on Sunday with at least 34 drones, the biggest drone strike on the Russian capital since the start of the war in 2022, forcing flights to be diverted from three of the city’s major airports and injuring at least five people.
