 TEHRAN, Iran (AP) — Iran's judiciary said Sunday that the brother of President Hassan Rouhani has been detained, and a Chinese-American citizen sentenced to 10 years behind bars for "infiltrating" the country. 
  
 The Chinese-American national was identified as Xiyue Wang, 37, and entered Iran as a student, according to Mizan Online, a website affiliated with the judiciary. Wang was not previously known to have been among the Americans detained in Iran. 
  
 Judiciary spokesman Gholamhosein Mohseni Ejehi announced both developments during a regular press briefing with local journalists. 
  
 He said Rouhani's brother, Hossein Fereidoun, was taken into custody over allegations of financial impropriety and is eligible for bail, but has not paid it yet. 
  
 Fereidoun is a close confidante of the moderate president, a cleric who changed his surname to Rouhani, meaning "spiritual," after joining the seminary decades ago. 
  
 Fereidoun was part of the negotiating team that ultimately sealed Iran's landmark nuclear deal with world powers in 2015, winning the country relief from international sanctions in exchange for limits on its atomic energy program. 
  
 The deal was unpopular with Iranian hard-liners, whose influence runs deep within the judiciary. They saw the nuclear deal as giving too much away in exchange for too little. 
  
 Fereidoun has long been a target of hard-liners, who have accused him of misdeeds including money laundering and misappropriation of government funds. 
  
 The unproven allegations were a flashpoint during the May presidential election, with the president's hard-line challengers demanding that the judiciary investigate accusations against Fereidoun. Rouhani trounced his nearest opponent to secure a second term in office in the first round of voting. 
  
 Wang faces 10 years in prison. 
  
 "It was verified and determined that he was gathering (information) and was involved in infiltration," Ejehi said earlier in the day, without naming him. 
  
 His identity was revealed later in the evening in a report on the Mizan website. 
  
 The judiciary spokesman did not elaborate on what specific charges led to the conviction, which he said could be appealed, or say when the verdict was handed down. 
  
 The U.S. State Department was not immediately able to provide any details on the case. 
  
 "The Iranian regime continues to detain U.S. citizens and other foreigners on fabricated national-security related changes," it said in a statement to The Associated Press. "We call for the immediate release of all U.S. citizens unjustly detained in Iran so they can return to their families." 
  
 The U.S. does not maintain formal diplomatic relations with Tehran and warns its citizens, particularly dual nationals, that they risk arrest or being barred from leaving Iran. 
  
 Wang is one of several Americans in Iranian custody. 
  
 Iranian-American art gallery manager Karan Vafadari was detained along with his Iranian wife last year. They have yet to be convicted of a crime. 
  
 Other American dual nationals who have been taken into custody and remain in Iran include Iranian-American businessman Siamak Namazi and his 81-year-old father, Baquer Namazi. They are both serving 10-year sentences for "cooperating with the hostile American government." 
  
 Another Iranian-American, Robin Shahini, was released on bail last year after staging a weeks-long hunger strike while serving an 18-year prison sentence for "collaboration with a hostile government." 
  
 Still missing is former FBI agent Robert Levinson, who disappeared in Iran in 2007 while on an unauthorized CIA mission. 
  
 Also in an Iranian prison is Nizar Zakka, a U.S. permanent resident from Lebanon who advocates for internet freedom. He lives in Washington D.C. and has done work for the U.S. government. He was sentenced to 10 years behind bars last year after being accused of espionage-related charges.

 Iran has sentenced a Chinese-born American dual national to 10 years in jail, accusing him of spying for the US government.

 Gholam-Hossein Mohseni-Eje’i, spokesman for the Iranian judiciary, said in a weekly press briefing in Tehran on Sunday that a US citizen who was also a national of a second country had been convicted for being “an infiltrating American agent”, according to Mizan Online, a news agency affiliated with the judiciary. 
  
 Mohseni-Eje’i did not identify the accused but Mizan later named him as Xiyue Wang, 37, a graduate student in history at Princeton. A statement issued by the university said it would do “everything it can to be supportive of Mr Wang and his family”. 
  
 “He had entered the country through a special connection but the ministry of intelligence identified him and arrested him,” Mohseni-Eje’i said. “It became clear that he was involved in the infiltration project and the initial court has sentenced him to 10 years but this could be appealed.” 
  
 Last year, Iran’s supreme leader, Ayatollah Ali Khamenei, warned against “an infiltration” from outside into the country’s political system. Since then, “infliltration” has become a code word for those accused by the authorities of having links with the west. 
  
 A string of dual nationals, mostly with additional Iranian nationality, have been accused of being part of the so-called infiltration network. Mohseni-Eje’i said Wang was “directly directed by the US”. 
  
 It was not possible to investigate the allegations against Wang independently. Iran has a history of making such allegations. 
  
  
  
 A Princeton statement emailed to the Guardian said: “Xiyue Wang is a fourth-year doctoral candidate … in the Department of History at Princeton University. His field is late 19th- and early 20th-century Eurasian history. He was in Iran last summer solely for the purpose of doing scholarly research on the administrative and cultural history of the late Qajar dynasty in connection with his PhD dissertation. 
  
 “We were very distressed to learn that charges were brought against him in connection with his scholarly work, and to learn of the subsequent conviction and sentence. We cannot comment more at the present time, except to say that the university continues to do everything it can to be supportive of Mr Wang and his family.” 
  
 The state department called for the immediate release of all US citizens in jail in Iran. 
  
 “The Iranian regime continues to detain US citizens and other foreigners on fabricated national-security related changes,” a press statement said. “The safety and security of US citizens remains a top priority. All US citizens, especially dual nationals considering travel to Iran, should carefully read our latest travel warning.”‎ 
  
 Washington Post reporter held captive sues Iranian government Read more 
  
 In January 2016, Iran released an Iranian-American Washington Post reporter, Jason Rezaian, who had been imprisoned for 18 months on spying charges. Rezaian has since sued the Iranian government, accusing it of hostage-taking and torture. 
  
 Mizan said Wang pursued espionage “through the cover of being a researcher”. The accused, the agency said, had been working on a digital archive for “the world’s biggest anti-Iran spying organization”. The allegations were based on an anonymous “informed source”, it said. 
  
 “He entered the country under the cover of a master’s student,” the report said, “but has been gathering secret and top secret [information]” for organizations such as “the US state department … the Harvard Kennedy School” and the British Institute of Persian Studies. Wang was accused of infiltrating Iran’s national archive and building a 4,500-page digital archive. 
  
 Other American dual nationals are currently held in Iranian jails. Among them is the Iranian-American Baquer Namazi, a former Unicef official sentenced to 10 years alongside his son, Siamak Namazi. United Nations chief António Guterres recently reached out to Iranian president Hassan Rouhani regarding their imprisonment. 
  
  
  
 Also in jail in Iran is Nizar Zakka, a Lebanese technology expert and US permanent resident held since September 2015 on spying charges. He was also sentenced to 10 years. |||||
