Tensions Escalate as North Korean Troops Allegedly Deployed to Russia

South Korea protested to Russia over reports of North Korean troops being deployed in Ukraine, calling it a violation of U.N. resolutions. South Korea's spy agency alleged that troops have arrived for training. The U.S. has not confirmed these reports, but diplomatic tensions rise.

South Korea has formally protested to Russia, alleging the deployment of North Korean troops to Ukraine. The foreign ministry summoned the Russian ambassador, voicing strong opposition against what it deemed a breach of United Nations resolutions and a threat to regional security.

Vice foreign minister Kim Hong-kyun delivered the protest to Ambassador Georgy Zinoviev, urging the immediate withdrawal of the troops. The move follows accusations by Ukraine that North Korea plans to send thousands of additional soldiers to support Russia's military efforts.

While the U.S. has not verified these reports, it acknowledged the potential seriousness if confirmed. South Korea insists on seeking a united international response, amid denials from both Russia and North Korea of any military personnel transfers.
