North Korea's Supreme Leader Kim Jong Un reportedly sent nearly 10,000 to 12,000 troops to aid the Russian invasion of Ukraine in the Kursk region in October

South Korea’s military says it suspects North Korea is preparing to send additional troops to Russia after its soldiers already deployed on the Russian-Ukraine war fronts suffered heavy casualties.

Britain's defense ministry said about 1,000 North Korean soldiers have been killed and around 3,000 more wounded fighting against Ukraine.

North Korea and Russia's deepening military relationship has sounded alarm in South Korea and the United States.

North Korea is presumed to be accelerating preparations for the additional deployment of its troops to Russia while continuing to push for potential launches of a spy satellite or an intercontinental ballistic missile (ICBM),
