Iran executed a nuclear scientist convicted of spying for the United States, an official said Sunday, acknowledging for the first time that the nation secretly detained and tried a man who was once heralded as a hero.
Shahram Amiri defected to the U.S. at the height of Western efforts to thwart Iran's nuclear program. When he returned in 2010, he was welcomed with flowers by government leaders and even went on the Iranian talk-show circuit. Then he mysteriously disappeared.
He was hanged the same week that Tehran executed a group of militants, a year after Iran agreed to a landmark accord to limit uranium enrichment in exchange for the lifting of economic sanctions.
Amiri first vanished in 2009 while on a religious pilgrimage to Muslim holy sites in Saudi Arabia. A year later, he reappeared in a series of contradictory online videos filmed in the U.S. He then walked into the Iranian-interests section at the Pakistani Embassy in Washington and demanded to be sent home.
In interviews, he described being kidnapped and held against his will by Saudi and American spies. U.S. officials said he was to receive millions of dollars for his help in understanding Iran's nuclear program.
Iranian judiciary spokesman Gholamhosein Mohseni Ejehi said Amiri "had access to the country's secret and classified information" and "had been linked to our hostile and No. 1 enemy, America, the Great Satan."
The spokesman told journalists that Amiri had been tried in a death-penalty case that was upheld by an appeals court. He did not explain why authorities never announced the conviction, though he said Amiri had access to lawyers.
News about Amiri, born in 1977, has been scant since his return to Iran. Last year, his father told the BBC's Farsi-language service that his son had been held at a secret site. Ejehi said Amiri's family mistakenly believed he received a 10-year prison sentence.
On Tuesday, Iran announced it had executed a number of criminals, describing them mainly as militants from the country's Kurdish minority. Then an obituary notice for Amiri circulated in his hometown of Kermanshah, a city some 500 kilometers (310 miles) southwest of Tehran, according to the Iranian pro-reform daily newspaper Shargh.
Manoto, a private satellite television channel based in London believed to be run by those who back Iran's ousted shah, reported Saturday that Amiri had been executed. BBC Farsi also quoted Amiri's mother saying her son's neck bore ligature marks suggesting he had been hanged by the state.
The Associated Press could not immediately reach Amiri's family.
His disappearance came as Western countries stepped up their efforts to impede Iran's nuclear program under the government of hard-line President Mahmoud Ahmadinejad. The U.S. actively tried to recruit nuclear scientists to defect. Later, four Iranian nuclear scientists were assassinated between 2010 and 2012, and Iran blamed the slayings on Israel and the West.
The Stuxnet computer virus, widely believed to be a joint U.S.-Israeli creation, disrupted thousands of centrifuges at a uranium enrichment facility in Iran.
In June 2010, a shaky online video emerged of Amiri saying he had been kidnapped by American and Saudi agents and was in Tucson, Arizona.
A short time later, he appeared in a professionally shot online video near a chess set, saying he wanted to earn a doctorate in America and return to Iran if an "opportunity of safe travel" presented itself. His wife and son remained behind in Iran.
"I have not done any activity against my homeland," he said. But soon, another clip contradicted that, and he appeared at the Pakistani Embassy.
Hillary Clinton, who was then the secretary of state, stressed that Amiri had been in America "of his own free will."
"He is free to go," she said.
