You've heard the stories. 10,000s of Yazidis stranded on Mt. Sinjar. The U.S. responding with air drops of aid. Then, the Pentagon declaring the siege over. But what happened in Sinjar? Why were civilians left unprotected without warning as ISIS militants advanced on their city? Is the crisis on the mountaintop over? Tune in for a special Iraq Matters report with Iraq-based researchers Christine van den Toorn and Nawaf, a Yazidi college student whose family fled Sinjar. Also included: an Iraq Update with Musings on Iraq blogger, Joel Wing, and the latest humanitarian developments.
