This is an old gore classic from the battle of Grozny, the capital city of the Chechen Republic. Grozny was heavily bombarded by the Russians which earned it a label of the most destroyed city on Earth. You can see from this short video that the extent of damage was severe.
The video shows an execution of a Russian soldier by the Chechen rebels. The soldier quietly speaks to the camera at night, and then the video skips to the jihadists cheering and laughing at him hanging. His hands were not tied behind or in front, they just let him helplessly choke to death.
The backstory has it that a group of Russian soldiers was ambushed by the Chechens and he was the only one to survive. The jihadists decided not to behead or shoot him, but instead have a bit of a laugh watching him hang.
Props to Best Gore member Small Man for the video:
