'Yezidische meisjes verkocht voor $10'

For the past week, Khandhar Kaliph's hands have trembled whenever his phone has rung. He nervously greeted his daughter, who had been kidnapped when the Islamic State (Isis) overran the Yazidi city of Sinjar. There was a minute of silence, before he broke down sobbing. "She said she is going to be sold as a slave this afternoon, for $10," Kaliph said, his tears dropping into the brown dust. "What can a father say to that. How can I help? We all feel so useless."
