Lured by rabbits, killed by snipers Russian troops has new "enemies" in Ukraine / VIDEO

Ukraine's intelligence agency the SBU has shared a video it says shows Ukrainian snipers killing Russian soldiers in a post which appeared to mock Russian claims about Kyiv using bioweapons labs.

On its Facebook page, the SBU posted a video captioned "combat rabbits lure orcs into position," using a derogatory term Ukraine uses to describe Russian troops, per Newsweek.

Without giving the location or date of the unverified video, the SBU said that sniper group A of its Central Special Forces unit had killed two Russian soldiers in the incident.

The grainy video which appears to come from a camera on a sniper rifle, shows white blobs moving across a cross-hair in the centre of the video and soldiers trying to run away.

The screen then jerks upwards, suggesting that the weapon had been fired, with the clip describing the scenario as demonstrating "Ukraine's secret weapon at work—war rabbits."

"During the training of enemy positions on the front lines, combat rabbits, trained in the secret laboratories of the Ukrainian special services, lured a group of Russians," the post in Ukrainian said, according to a translation.

This is likely to be a reference to claims by Moscow that bioweapons research is being undertaken in Ukraine in cahoots with the US. One of the claims suggested that Kyiv was developing dangerous infections using migratory birds. The claims have been dismissed internationally and by experts.

The rest of the SBU's Facebook post said: "The goal was completed, the combined group returned to the base without losses!"

It suggests that viewers watch until the end of the clip which shows a graphic of two rabbits in combat fatigues walking towards a descending helicopter.
