Ukraine has been interrogating two North Korean soldiers after seizing the pair in Russia's Kursk region - the first time it has announced the capture of North Korean troops alive since their entry into the war last autumn.

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.

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,

While Russia has received support from various allies, recent reports suggest a growing presence of North Korean troops on the battlefield. Their involvement raises questions about their role in the conflict and the equipment they bring to the fight.
