I don’t know much about the background to this video, but on a scale of probabilities, I’d think that Syria is the most likely location, as that’s where jihadists are most active at present. However it could be from any other Middle Eastern country as well.
The video shows apparent jihadists stabbing a wounded man repeatedly in the stomach. I don’t speak any Arabic, but I recognize word “Murtaddin“, which the jihadists use to address the man. Murtaddin is an apostate from Islam, according to Oxford University Press Encyclopedia.
After burring the blade in the victim’s stomach, the stabber jerked it about to cause more internal trauma. And since I doubt they rushed the victim to hospital after the video ended, I think it’s fair to assume he’s dead even though the moment of death is not in the video.
Props to Best Gore member @natural-selection-2 for the video:
