TEHRAN (NYTIMES) - A US student from Princeton University was arrested in Iran and has been sentenced to 10 years in prison on charges he was spying for the United States, an Iranian judiciary official said on Sunday, an action bound to aggravate relations between the two countries.
The arrest and sentencing of the American, Xiyue Wang, a graduate student in history, was announced months after he had vanished in Iran, where he was doing research for a doctoral thesis. There had been rumours of his arrest, but the announcement on Sunday from Iran was the first official confirmation.
A spokesman for Iran's judiciary, Gholam Hossein Mohseni-Ejei, said at a weekly news conference that one of "America's infiltrators" had been prosecuted, but he did not identify Wang by name or nationality. The judiciary's Mizan News Agency provided his name and his age, 37, saying he had "spider connections" with US and British intelligence agencies.
Mizan also said Wang, whom it described as fluent in Persian, had digitally archived 4,500 pages of Iranian documents and had done "super confidential research for the US Department of State, Harvard Kennedy School and British Institute of Persian Studies".
A Princeton spokesman, Daniel Day, confirmed that Wang, a US citizen of Chinese descent, was the man arrested in Iran. "That's our student," Day said in a telephone interview.
He also said the university had known about the arrest for months but had been trying to work quietly to have Wang freed.
In a statement issued after news of his arrest and sentence was reported, the university said Wang was a fourth-year doctoral candidate specialising in 19th- and early 20th-century Eurasian history who had been arrested last summer while doing scholarly research in Iran on the Qajar dynasty.
"Since his arrest, the university has worked with Mr Wang's family, the US government, private counsel and others to facilitate his release," the statement said.
"We were very distressed by the charges brought against him in connection with his scholarly activities, and by his subsequent conviction and sentence," the statement continued. "His family and the university are distressed at his continued imprisonment and are hopeful that he will be released after his case is heard by the appellate authorities in Tehran."
News of Wang's sentencing came as the judiciary spokesman also announced that the brother of President Hassan Rouhani of Iran had been arrested in a corruption inquiry, in what appeared to be a move by Rouhani's hard-line rivals to undermine and embarrass him.
The brother, Hossein Fereydoun, had been one of Rouhani's close aides.
The arrests suggested ominous new pressure on Rouhani, a moderate cleric who was re-elected to a second four-year term a few months ago.
His re-election was seen as a referendum vote by Iranians for more cooperation with other nations, including the US, despite the entrenched anti-American hostilities harbored by other powerful interests in Iran, including its supreme leader, Ayatollah Ali Khamenei; the judiciary and intelligence services; and the Islamic Revolutionary Guards Corps paramilitary force.
The news of the arrests coincided with the second anniversary of Rouhani's signature achievement: the agreement with the US and other world powers to curb Iran's nuclear activities in return for the easing of economic sanctions that have long isolated Iran.
The agreement has not produced the desired economic boom in Iran, giving political ammunition to conservatives who opposed the pact. Critics of the agreement in the US have also complained, saying it is too weak.
President Donald Trump, who has escalated tensions with Iran, repeatedly assailed the nuclear agreement during his 2016 campaign as "the worst deal ever". He must decide by Monday whether Iran is honouring the deal, under a US law that requires the administration to certify every 90 days that Iran is complying with the terms.
Fereydoun, a former ambassador to Malaysia, has long been considered a potential political vulnerability for Rouhani over allegations of nepotism and cronyism.
Hard-liners accused Fereydoun more than a year ago of improper dealings with money-changing companies during the final years of the administration of Rouhani's predecessor, Mahmoud Ahmadinejad. They said Fereydoun had continued those dealings while serving as an adviser to Rouhani.
Fereydoun also has been accused by hard-liners of using his influence to place colleagues in high-paying positions, and of exploiting his connections to gain a coveted spot in a doctorate program at an Iranian university. He has denied the accusations.
"Rouhani and the reformists won a landslide victory in the May presidential elections, yet this detention makes clear the conservatives are still strong and can lash out," said Cliff Kupchan, chairman of the Eurasia Group, a political risk consultancy in Washington. The president's brother, Kupchan said, is "low-hanging fruit for conservatives seeking to cut Rouhani down to size."
Iran's judiciary spokesman, Mohseni-Ejei, said on Sunday that Fereydoun had been arrested the day before, according to the judiciary's news agency, and because he was not able to provide bail, he was jailed until he could do so.
Mohseni-Ejei did not specify the bail amount or the precise charges.
Referring to Wang, the spokesman said the person sentenced in the espionage case had been "identified and arrested by the Intelligence Ministry's forces, and it was established that he was gathering information and was involved in spying activities".
Once the verdict is final, Mohseni-Ejei said, he would "be able to explain more about this person's intentions and activities," adding: "Unfortunately he was taking direct orders from America."
In a statement, the State Department said: "The Iranian regime continues to detain US citizens and other foreigners on fabricated national-security related changes. We call for the immediate release of all US citizens unjustly detained in Iran so they can return to their families."
A number of US citizens, mostly Iranian-American dual citizens, have been imprisoned in Iran over the years on similar charges.
Five were freed when the nuclear deal took effect in January 2016, including Jason Rezaian, a former Washington Post correspondent in Tehran. But others continue to languish in Iranian prisons, despite repeated calls by the US and others to release them.
The most notable prisoners include Siamak Namazi, an Iranian-American businessman who had called for improved relations; his father, Baquer Namazi, a former UNICEF diplomat; and Nizar Zakka, a Lebanese citizen with permanent US residency.
Zakka's lawyer in the US, Jason Poblete, said his client had been on a hunger strike for the past three weeks. Zakka was sentenced a few months ago to 10 years in prison.
