As the title above.According to the cameraman this was captured by a drone, you can also the shadow of the drone.The cameraman said that he surrendered himself through putting the vest and weapons down ( you can see when he points at the screen with the mouse on 0:17 ), he also took his clothes off so the Iraqi forces does not think that he is a suicide bomber. As you can see at the end of the video it shows where the Iraqi forces was, it was a very long distance between the Iraqi forces and this ISIS fighter.
