A US researcher has been sentenced to 10 years in prison after being convicted of spying, CNN reported on Monday.
Princeton University identified the man as Chinese-born Xiyue Wang, an American citizen and graduate student in history.
Wang was arrested in Iran last summer while doing scholarly research in connection with his PhD dissertation.
Earlier Sunday, Iranian judicial spokesman Gholamhossein Mohseni-Ejheie, initially identified the convicted man's nationality as Iranian-American.
Mohseni-Ejheie, said he was a citizen of the United States and a country other than Iran.
The dates of Wang's trial have not been disclosed. He was arrested and put on trial for "gathering information," and the sentence can be appealed, Mohseni-Ejheie added.
According to Iranian law, a convicted person has 20 days to appeal a sentence.
