I have virtually no backinfo on this video. By the sound of it, it appears to be from an Arabic country, and shows an aftermath of an unspecified form of carnage that took place on the road at night. It could have been a traffic accident, but could also have been an attack of sorts.
There is a general blood bath throughout the accident scene and of multiple men down, only one is still capable of moving. He’s dressed in light clothes, but they are utterly drenched in blood. His right arm appears to have been amputated at the elbow, but there is probably more to his injuries.
He’s in terrible agony as his mates lie around him lifeless. Most of them are likely dead, and even though some give faint reactions to passers-by trying to comfort them, they probably don’t have a whole lot of life left in them.
Props to Best Gore member @nikish for the video:
