Although reports suggest North Korean soldiers have suffered heavy losses fighting Ukrainian forces, South Korea's military suspects reinforcements are coming.

The soldiers appear to have been pulled back from the front lines in Kursk after suffering heavy casualties during barely a month of combat, Ukrainian officials said.

Ukraine's special operations forces have not seen North Korean troops on the battlefield in Russia's Kursk region for around three weeks, suggesting they have been forced to withdraw after taking heavy losses,

Ukranian reports indicate that the North Korean soldiers previously encountered have withdrawn from the frontline. This report is limited to the Kursk region, where a large part of the recent fighting has been going on.

In the fog of war, whispers from the Ukrainian front lines reveal a curious absence. The once-present North Korean troops have seemingly vanished from the scene.
