Four Iranian nationals and two dual nationals were sentenced to 10 years in prison each over charges of espionage and collaboration with the US government, a media report said on Wednesday.
The Iranian judiciary has identified two of the convicts as Iranian-American Siamak Namazi and his 80-year-old father Baquer Namazi, and the others as Nazaar Zakaa, Farhad Abd-e Saleh, Kamran Qaderi and Alireza Omidvar, the Xinhua news agency reported.
Following the release of the news, the US State Department demanded the "immediate release" of the two Iranian-Americans by Iran.
Siamak Namazi was arrested in October 2015 and his father, Baqer Namazi, was detained in February this year.
Reportedly, Siamak formerly worked for the Sharjah-based Crescent Petroleum oil and gas company.
Baqer is a former Iranian provincial governor and served as a Unicef representative in Somalia, Kenya, Egypt and other countries.
