Ukraine Special Forces, who are fighting in the West Kursque area of Russia, told the BBC that they had not seen the North Korean army for the past three weeks.
A spokeswoman said that it was likely that he had withdrawn after suffering significant losses.
Last week, western officials told the BBC that 1,000 out of about 11,000 units sent from North Korea to fight for Russia died in just three months.
North Korea and Russia have not commented.
On Friday, Ukrainian Spokesman, a Spokesman, told the BBC that he only mentioned the areas in the Cruch area where his army is fighting.
The spokesman did not say the length of the forefront.
And this is not an overall picture, but suggests important North Korean victims.
Apart from that, the New York Times also reported that North Korea was separated from the forefront.
The newspaper says that the US officials may not be permanent, and the soldiers have been trained and the Russians avoid such heavy casualties. He said he could return after thinking of a new method to be expanded.
According to a report from South Korea’s Intelligence report, North Korea is not ready in the reality of the modern war and is particularly vulnerable to the target of the Ukrainian drone.
Russia’s President Vladimir Putin and North Korea’s leader Kim John Ann have signed a two -way relationship in recent months and signed security and defense treaty.
The support of Pyongyang Moscow is currently extending to a large amount of ammunition and weapons.
Last August, the elite Ukrainian army started a lightning attack on a Cruch and seized more than 1,000 square kilometers (386 square miles) in Russian territory.
Since then, the Russian army has been able to capture a considerable mass in the area.
Kiev’s surprise invasion was to change the dynamics of the war.
Initially, in the eastern Ukraine, it was first hoped to alleviate the pressure to the other part of the forefront of 1,000 km or more (620 miles).
Moscow has been seizing many villages in the Donetsk area in a few weeks, although it is no mercy in the eastern part.
Currently, Kiev is aiming to hold the land that is occupied by the Cruch as a leverage that may be a ceasefire with Moscow and a peace negotiations.
Russia started Ukraine’s full -fledged invasion in February 2022.
