ISIS has published documents justifying the enslavement of Yazidis as spoils of war, and activist Khider Domle has interviewed dozens of women and girls who have fled their captivity.
“Every time a woman escapes we learn more about how they are using Yazidi women,” he said.
Domle said the women, especially those who end up in ISIS strongholds in Syria, tend to be traded or sold three or four times as fighters move to different locations and leave the women behind.
“Some are sold for weapons, or for just $10, or 10 cigarettes,” Domle said.
Some ISIS fighters send pictures of the women and girls to their families, either to taunt them or demand a ransom.
“Jeelan,” whose name also has been changed to protect her identity, escaped her ISIS captors in August, along with her nine-year-old sister.
