Beneath a crumbling soccer stadium in Raqqa, in northeast Syria, is a maze of narrow corridors and underground cells where ISIS once held its prisoners. In this installment of our “Behind the Lines” podcast series, Mother Jones senior reporter Shane Bauer tours these abandoned tunnels with a former prisoner who recounts the atrocities that happened beneath the stands where he’d watched soccer matches as a boy. Pro-ISIS graffiti still covers the walls of the cramped rooms were prisoners were kept in darkness, released only to be interrogated, tortured, and fed ISIS propaganda. While some prisoners made false confessions and were beheaded, others tried to save their lives by accepting their captors’ religious message; some escaped by joining ISIS. In this episode, Bauer provides an inside look at the place where ISIS held its captives and created new recruits.
