This Christmas, there will be an empty chair at the table for Rafif's family in Iraq. Everything Rafif knows about her dad she has heard from her mum, and other people who knew him. Because when Raddif ran towards that bus filled with Christian students, warning them of the planned bombing, he saved a lot of lives but was himself killed. It would be a few more months before Rafif was born. She’s 11 now, and she never got to meet her dad. She’s one of many Christian children across the world suffering the long-term effects of persecution.
