In this Wednesday, Feb. 3, 2017 photo, in Tunis, Tunisia, Faouzi Trabelsi shows a photo of himself posing with his grandson, Tamim Jaboudi, who has been trapped in a prison in Libya since his parents, both Tunisians who left home to join the Islamic State group, died in an American airstrike in February 2016. He is among hundreds of children of Islamic State’s foreign fighters in limbo, despite his grandfather’s efforts to free him. (AP Photo/Ons Abid)
