Ukraine probes video purported to show soldier's beheading

Ukraine launched an investigation Wednesday into a gruesome video circulating on social media that purportedly shows the beheading of a Ukrainian soldier.

The video spread quickly online and sparked outrage from Ukrainian officials. The Kremlin called the footage “horrible” but said it needed to be verified.

The Associated Press was not able to verify the authenticity of the video or the circumstances of where and when it was shot.

Meanwhile, a Russian defense official claimed that fighters from Russia's paramilitary Wagner group have seized three districts of Bakhmut, the embattled city that for months has been the focus of Moscow's grinding campaign in the east.

The video circulating online appears to show a man in green fatigues wearing a yellow armband, typically donned by Ukrainian fighters. He is heard screeching before another man in camouflage uses a knife to decapitate him.

A third man holds up a flak jacket apparently belonging to the man being beheaded. All three men speak in Russian.

Since Russia's forces invaded Ukraine more than a year ago, they have committed widespread abuses and alleged war crimes, according to the United Nations, rights groups and reporting by The Associated Press.
