One complication of the war to oust the Islamic State from Iraq has been the behavior of often-Iranian-trained Shi’ite militias. They’ve frequently been accused of abusing, torturing, even killing innocent Sunni civilians. That’s why they’ve all been told to steer clear of the Battle for Mosul and concentrate on IS units in the hinterlands outside the city. Kenneth R. Rosen of the NY Times spent time recently with one Shi’ite militia group in the desert, near the Syrian border. Their denials of bad behavior, Rosen says, didn’t account for a hidden prison camp, where Human Rights Watch says, those very abuses have been committed.
