A horrific video allegedly showing soldiers burying a man alive has been posted online. It shows four men wearing camouflage uniforms and balaclavas throwing the man into an open grave.

The man is clearly alive and his feet can be seen moving once he is lying in the ground. A voice can reportedly be heard in the background saying in Ukrainian: 'He is not dead yet.'

The shocking film was first broadcast on Russian channel TV Zvezda, which claims it shows Ukrainian soldiers murdering a pro-Russian separatist, reports Daily Mail.  

The 'soldiers' shovel earth on top of their 'victim' until he is apparently completely buried.

One then rams his shovel upside down into the soil as a rudimentary grave marker.

The latest video follows on from a clip in February this year, also shot in Ukraine, that reportedly showed Russian militants torturing a drug dealer.

The victim was seen being brutally whipped while tied to a wooden post in southern Ukraine's Donetsk Oblast region. He begs for his life as he is repeatedly beaten with electrical cables by a masked militant, leaving him with a bruised and bloodied back.

The man was then reported missing and presumed dead following the shocking 'punishment' in the town of Communar, which is currently occupied by pro-Russian rebels.

The latest video, this time from pro Ukrainian forces, has gone viral after being posted on video-sharing websites however many viewers have doubted its authenticity.

They point out that TV Zvezda is a propaganda channel run by the Russian Ministry of Defence and say viewers should be sceptical.

Tensions remain high between Ukraine and Russia following the annexing of the Ukrainian territory of Crimea by Russia in 2014.

It followed a military intervention by Russia in Crimea, which took place in the aftermath of the 2014 Ukrainian revolution and was part of wider unrest across southern and eastern Ukraine.

Ukraine considers the annexation to be a violation of international law and agreements by Russia and it has been condemned by the UN and many world leaders.
