Kim Jong Un has sent thousands of troops to reinforce the Russian military, including to the Kursk border region, where Ukrainian forces seized territory earlier this year.

But Ukraine's position in the region could soon be in jeopardy due to 'suicidal charges' from North Koreans, after Kyiv already lost roughly 40 per cent of the territory it seized in Kursk, according to the Times.

Drone footage shows the Russian meatgrinder tactic in action, with two dozen North Korean soldiers seen slowly jogging towards the Ukrainian front line in clusters across an open, snow-covered battlefield.

They didn't try to seek cover, which was 'like a dream for our mortars and machinegunners,' Ukrainian veteran Vitaliy, 35, told the Times. 

Vitaliy fought in the battle of Bakhmut, which saw waves of Russian murderers and rapists being sent to their deaths as apparent cannon fodder.

'The Wagner group had a simple order: advance or die. It looked like exactly the same thing for the Koreans,' he said. 

The Khorne Group - an organisation linked to Kyiv forces in the 116th separate mechanised brigade and 95th air assault brigade -, shared footage showing what appeared to be North Korean soldiers dumbfounded by a Ukrainian FPV drone above them.

Another dark clip showed a line of what were said to be the bodies of soldiers from Pyongyang lying in blood-covered snow alongside slain Russians after their troop was all but wiped out. 

The Khorne Group said: 'The long awaited North Koreans. Weakness and bravery are their tactics, their trump card is good fitness.' They were 'applying the same tactics as 70 years ago', Khorne Group added, alluding to the Korean War.

At least 100 North Korean soldiers deployed to support Russia's war effort in Ukraine have been killed since entering combat in December, South Korean lawmakers claimed yesterday.

Ukrainian and South Korean officials say the North Koreans have proven a burden to Russian forces due to their outdated battlefield tactics, while inexperience with drone warfare makes them easy targets for Kyiv's battle-hardened warriors.

It comes as Ukrainian President Volodymyr Zelensky declared Russian troops were 'burning the faces' of dead North Korean servicemen to conceal their identities, sharing macabre images to illustrate his claim.

Citing a report by South Korea's intelligence services, MP Lee Seong-kweun said yesterday: 'In December, they (North Korean troops) engaged in actual combat, during which at least 100 fatalities occurred.
