Soldiers fighting for Ukraine describe facing relentless waves of determined North Korean troops, Russian units with improved tactics, and Ukraine’s own struggles with exhaustion and sinking morale.

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

North Korea has not responded to reports of its troops captured or killed by Ukraine forces. It has never publicised the deployment or large shipments of North Korean artillery shells and other weapons sent to Russia to help its war against Ukraine, although they marked the country’s first intervention in a major armed conflict overseas in decades.

South Korea's military said on Friday that it suspects North Korea is preparing to send more troops to Russia to fight Ukrainian forces, even after suffering losses and seeing some of its soldiers captured.

North Korea is poised to send more than 100 of its fearsome M1989 Koksan howitzers to Vladimir Putin's troops in Ukraine, a top general has claimed.

British intelligence has reported that one-third of the troops deployed alongside Russian forces in Ukraine are already out of action. Pyongyang sent a contingent of 12,000 soldiers to Russia to assist local forces in regaining lost territory in the Kursk region,
