This report, authored by the Free Nazanin Campaign and REDRESS, details for the first time the systematic pattern of human rights abuses committed through Iran’s hostage-taking practice. The report draws in part from detailed testimonies from 26 victims of hostage-taking or their family members, who shared their experiences from their initial detention and interrogation through illegitimate legal proceedings, abuses suffered during imprisonment, false and abusive propaganda by the regime, and their use as “diplomatic assets”.
