The video shows a male corpse lying in the dirt, one end of a rope tied around his legs, the other fastened to the back of an armored Humvee.

Men in Iraqi military uniforms mingle by the vehicle. Someone warns there might be a bomb on the body. One hands another his smartphone. Then he stands over the body, smiles, and offers a thumbs-up as his comrade takes a photo. The Humvee starts to move, dragging the dead man behind it into the desert.

The short video was shown to Reuters last week by an Iraqi national police officer. It captures what appear to be Iraqi soldiers desecrating the corpse of a fighter from the Islamic State of Iraq and Levant (ISIL), a group reconstituted from an earlier incarnation of al Qaeda in Iraq.
