Former Iran hostage Barry Rosen goes on hunger strike to campaign for prisoners in Tehran

A survivor of the 1979 Iran hostage crisis will embark on a hunger strike in solidarity with those unlawfully detained by the Iranian regime. Barry Rosen, a senior adviser at the advocacy organisation United Against Nuclear Iran, said he will travel to Vienna on Tuesday to stage his protest. Officials are engaged in long-running talks with Tehran in the Austrian capital over a resurrection of the 2015 nuclear deal Iran agreed to with world powers. The hunger strike will mark 41 years since Mr Rosen’s release when, as the US press attache in Iran, he was one of 52 Americans held hostage at Washington’s embassy in Tehran for 444 days.
