Iranian authorities have denied the appeal of a Princeton University student who had been convicted on espionage charges and sentenced to 10 years in prison, the university and his wife said on Thursday.

Xiyue Wang, a history doctoral student and U.S. citizen who was conducting dissertation research in Iran in 2016 when he was detained by Iranian authorities, was accused by Iran of "spying under the cover of research," a claim his family and university deny.

"Iranian authorities have denied Xiyue Wang's appeal of his conviction and 10-year prison sentence for espionage that he did not attempt or commit," Princeton University said in a statement. "We are distressed that his appeal was denied, and that he remains unjustly imprisoned."
