Apparently this is an aftermath of trauma by gunshot to the hand, although I’m pretty sure the snackbarist says something fundamentally different in his commentary. The video is form Syria so that’s to be expected.
I won’t lie to you, that looks painful as all fuck. The victim has a very long road to recovery ahead of him, but he can count himself lucky cause it’s his right hand that took the shot. As such, he can still give himself a stranger.
