The child who saved my life – and vanished

When so-called Islamic State attacked northern Iraq, Hogir Hirori - a documentary maker and refugee from the region - went back there to record what was going on. He came across a young girl who was seriously ill, and decided to drop everything to help her. But then she vanished. And Hogir now had a mystery to solve. Jo Fidgen takes up the story.
