From BBC Sounds, BBC Asian Network and CBC. Syria. 2018. ISIS is on the brink of defeat. Two-year-old Salmaan disappears amid the bombardment. In London, his grandfather desperately searches for answers. After the war against the Islamic State was won, what became of the children of its fighters? There are thousands of kids like Salmaan, with roots in Canada, the U.K., the U.S. and beyond — They were taken to IS or born there. Now they are trapped there without a way back home. Investigative reporter Poonam Taneja has covered the terror group for a decade and now embarks on a dangerous journey to find out what happened to Salmaan and all the kids like him, left behind in the Syrian desert. And she speaks to the grandparents trying to get them home. Bloodlines will be released weekly, beginning Oct. 23, 2023.
