Yes. I remember that great evil. I was engaged in supporting the good guys there for 7 years. It went silent when ISIS was finally defeated in North Eastern Syria.
Of course they are still holding the survivors in prison, had a prison break recently. Nobody in their home countries want them back. So the Kurds are stuck with them and not given much help with that.
I only saw the pictures, and that was bad enough. Seven years. Brr. Must give you nightmares.
