An American researcher was convicted of spying Sunday in Iran and sentenced to 10 years in prison.
Xiyue Wang, a Chinese-born American citizen, is a graduate student studying history at Princeton University.
School officials said that Wang was doing scholarly research for his Ph.D. dissertation before he was arrested in Iran last summer.
"We were very distressed by the charges brought against him in connection with his scholarly activities, and by his subsequent conviction and sentence," university spokesman Daniel Day said.
According to CNN, Iranian judicial spokesman Gholamhossein Mohseni-Ejheie said in a statement that Wang was arrested for "gathering information," and the sentence can be appealed.
Wang is the latest American to be charged with spying in Iran. In 2016, U.S.-Iranian citizen Reza "Robin" Shahini was convicted of spying and sentenced to 18 years in prison.
