The Ukrainian special forces fought in western regions in western Russia and told Broadcasting Corporation that they did not see any North Korean troops there in the past three weeks.

A spokesman said they were likely to withdraw after suffering heavy losses.

Last week, Western officials told Broadcasting Corporation (BBC) that among the 11,000 soldiers sent from North Korea to Russia, they were killed 1,000 in just three months.

North Korea and Russia have not published comments.

On Friday, a spokesman for Ukraine Special Forces told Broadcasting Corporation that he only referred to the area where the troops in the Kursk region were fighting.

The spokesman did not say how long the front line was.

Although this is not complete, it does show important casualties in North Korea.

In addition, the New York Times also reported that the North Koreans were pulled open.

The newspaper quoted US officials as saying that withdrawal may not be permanent. After receiving additional training or Russians, soldiers can return to avoid such heavy casualties.

It is due to reports from Korean intelligence that the Korean people are not prepared for the reality of modern war, and they are particularly vulnerable to the Ukraine drone.

Russian President Vladimir Putin and North Korean leader Kim Jong UN have deepened bilateral relations in recent months and signed a security and defense treaty.

The assistance of Pyongyang to Moscow has now expanded to a large number of ammunition and weapons.

Last August, the Ukrainian elite army launched a lightning offensive in Kurusk, occupying more than 1,000 square kilometers (386 square miles) of Russian territory.

Since then, the Russian forces have managed to recapture most of the region.

Kiev’s surprising invasion aims to change the motivation of war.

It was originally hoped that the operation would reduce the pressure of more than 1,000 kilometers (620 miles) of the front line, especially in eastern Ukraine.

Moscow continues to maintain its unremitting unremitting efforts in the East-Although it is slow, it has occupied many settlements in the Donetsk area in recent weeks.

Now, Kyiv hopes to persist in the land occupied by Kursk as a leveraged role in a suspension or peaceful negotiation with Moscow.

Russia began to invade Ukraine in February 2022.
