'I Paid $90,000 To Free My Family From IS'

Khalid Taalo Khudhur al-Ali fled with his wife and children as Islamic State militants attacked their town in Iraq in 2014, but 19 other members of his family were captured. 

Over the last four years he has paid $90,000 for the release of 10 of them. But now, after the defeat of IS, he fears that any survivors may be beyond his reach.
