At least 10 dual and foreign nationals or Iranian citizens are known to be imprisoned in Iran as of April 2020, according to research by the US-based Center for Human Rights in Iran. Despite the fact that many of them have serious health issues only two – Nazanin Zaghari-Ratcliffe and Aras Amiri – were temporarily released when Iran furloughed more than 100,000 prisoners out of concern for Covid-19.
