ISIS militants imprisoned Yazidi women in Syrian desert dungeon

Islamic State militants imprisoned Yazidi women in a dungeon buried underneath the desert in northern Syria, it has emerged.
Sky News reporters were shown a small makeshift prison cell hidden beneath the sand, where dozens of women from the Yazidi minority group are believed to have been held. It is not known where they are now.
Yazidism is an offshoot of Zoroastrianism, which blends ancient religious traditions with both Christianity and Islam. According to ISIS doctrine, they are "devil-worshippers", and members of the group have been systematically persecuted by militants.
Last month, a number of mass graves were found in the Iraqi town of Sinjar, believed to contain the bodies of over 200 Yazidis.
Hundreds of thousands of residents were forced to flee from Sinjar when Kurdish troops withdrew in August last year, leaving them vulnerable to attack, and thousands were killed. Many women and girls were taken as sex slaves, and horrifying accounts have emerged of their treatment at the hands of ISIS militants. A 22-year-old Yazidi woman told CNN in October that she was raped by 12 militants while in captivity, who believed that a woman would become Muslim if she was raped by at least ten men.
