Ukrainian President Volodymyr Zelenskyy said he’s willing to hand over the soldiers to North Korea, if Kim Jong Un arranges for an exchange with Ukrainian prisoners of war in Russia.

There is mounting evidence from the battlefield, intelligence reports and testimonies of defectors that some North Korean soldiers are resorting to extreme measures as they support Russia's three-year war with Ukraine.

It comes after Ukraine released footage of two captured men, reportedly North Korean soldiers fighting for Russia.

At least 300 North Korean soldiers sent to aid Russia in its war against Ukraine have been killed and another 2,700 have been injured, South Korea's spy agency told lawmakers on Monday.

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.

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.

North Korea is reportedly preparing to send more troops to Russia to fuel the war in Ukraine, even after significant losses, the South Korean Joint Chiefs of Staff (JCS) reported.

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

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

Kim Jong Un's soldiers have joined the Russians in the war against Ukraine. Although North Korean military personnel are dying in large numbers in the battles, they have developed a method for destroying Ukrainian drones.
