Orphans of ISIS

The children of the notorious jihadist Khaled Sharrouf were taken to the self-declared IS caliphate in 2014. First seem by the world after their father published infamous pictures of his eldest son holding the severed head of a prisoner, sending shockwaves around the world. For five years, their grandmother Karen Nettleton has been trying to reach the children and bring them home. Now in Syria, she's making a last-ditch effort to save them from the cramped and dangerous al-Hawl refugee camp.
