Citing "new data" on the deployment of North Korean troops to Russia, Zelenskiy said they were "being selected for training and subsequent deployment ⁠to Russia." The Ukrainian president said in August that up to 50,000 North Korean soldiers could be sent to fight for ⁠Russia, and called on South Korea to provide support for Ukraine's air defense.

South Korea announced ​in July a $100 million aid package for Ukraine, although it ‌excluded lethal weapons.

Zelenskiy's comments on Monday came after Seoul ‌and Kyiv were ‌at odds over his announcement last week ‌that Ukraine had transferred two captured ​North Korean soldiers to South Korea.

Seoul expressed regret over ⁠his announcement, citing an agreement to keep the transfer confidential. South Korea also protested against what it called a false ⁠statement from ​the Ukrainian presidential office ⁠denying that such a confidentiality agreement existed.

North Korea has sent an ​estimated 14,000-15,000 troops to support Russia's war in Ukraine since 2024, according to Ukrainian and South ⁠Korean estimates, with most deployed ⁠in ⁠the Kursk ‌region to help repel a Ukrainian incursion.

Pyongyang has also supplied Russia with millions of artillery and mortar rounds, as ​well as ballistic missiles, long-range artillery systems and multiple-launch rocket systems, according to Ukrainian and independent assessments. (Reuters)
