NEW YORK: Families and supporters of Americans detained in Iran say their loved ones face new dangers during the intensifying war, including the risk of becoming unintended casualties of Israeli and American bombardment or victims of retaliation from Iran’s repressive regime. “For Americans imprisoned in Iran, this is about as terrifying a moment as it gets,” said Siamak Namazi, an Iranian American who was detained for nearly eight years before being released as part of a deal with the US in 2023.
