Iraq conflict: IS 'trafficking Yazidi women for sex'

More than 3,000 Yazidi women and children have been captured by Islamic State militants and are being trafficked for sex, the BBC has learned.

Those who have escaped have spoken of being raped, tortured and starved.

Tens of thousands of members of Iraq's Yazidi minority fled from Islamic State (IS) in August and are now homeless.

Human rights activists say more than 5,000 men, women and children are still missing.
