A grainy video posted to Twitter shows a bearded man, his hands raised, on his knees, pleading for his life. A few seconds later, a soldier in desert fatigues, and allegedly from the Iraqi Army's 16th Division, enters the frame and pushes the petrified man over the edge of a cliff on to the banks of a river down below. The man appears alive, just, but as he attempts to slither to cover, the soldier unleashes a volley of a dozen or so rounds, leaving his bloodied body lifeless. His crime is unclear, though without jury nor trial his tormentors have accused him of being a member of Isis.
It is barely two weeks since Iraqi Prime Minister Haider Al-Abadi declared Mosul officially liberated from Isis. After a near nine-month campaign that has seen some of the fiercest urban warfare since World War Two, Iraqi government forces have secured a small triumph.
