The U.S. has around 28,500 soldiers stationed in South Korea. A report by the Chicago Council on Global Affairs shared with Newsweek this week found that over half of Americans (51 percent) back using American forces troops to defend South Korea if North Korea invaded.

Over 10,000 North Korean soldiers are preparing to fight Ukraine, with at least 1,500 troops having already arrived in Russia.

Ukraine says the footage shows North Korean troops "being outfitted in Russian gear" at Russia's Sergievsky training ground.
