When Rosa, now 14, asked her Islamic State captors about her younger sisters, Bushra, 12, and Suhayla, 7, she was told they had been killed for misbehaving.

The sisters were finally reunited on Sunday, more than three years after being taken by the militants in an assault on Sinjar, the Yazidi heartland, on Aug. 3, 2014.
