The Committee to Protect Journalists (CPJ) has called on the Iranian government to immediately release four detained journalists, three of whom it said had US-Iranian nationality.
Two of the detainees are Jason Rezaian, the Tehran correspondent for the Washington Post, and his wife Yeganeh Salehi, a correspondent for the United Arab Emirates-based newspaper the National, the CPJ said in a statement.
Iran is known to have a dismal record with regard to its treatment of imprisoned journalists.
Rezaian, 38, has dual US-Iranian nationality and has worked for the Post in Tehran since 2012. The Post reported that Salehi “has applied for US permanent residency”.
Iran does not recognise dual citizenship.
US State Department deputy spokeswoman Marie Harf said Washington was aware of the reports of the detention of three US citizens in Iran; saying that they were not able to comment further due to privacy concerns.
Besides the four, there are 35 journalists in prison in Iran, according to CPJ.
