Almost 10 years after the Islamic State group launched its conquest of the Mount Sinjar region in Iraq as part of its takeover of the country, a new film tells the stories of the Yazidi people, who suffered a genocide under the extremists' rule. Several thousand Yazidis were killed or captured, while half a million others fled. The film "Sinjar, the Birth of Phantoms" talks to survivors about how their lives have been turned upside down, and how they still fear violence could return. Its director Alexe Liebert told how she hopes the film will ensure their voices are heard.
