The Yazidi women held as sex slaves by IS
It is almost a year since thousands of Yazidis fled to Mount Sinjar, in northern Iraq, as Islamic State fighters entered their villages.
Some escaped but many Yazidi men were killed and young women and girls are still being held as sex slaves by the group.
Some of the girls have managed to escape and have been speaking to the BBC about their ordeals, as Sue Lloyd-Roberts reports.
