TEHRAN, Iran — An Iranian court has convicted an American man of working for the CIA and sentenced him to death, state radio reported Monday, in a case adding to the accelerating tension between the U.S. and Iran.
Iran charges that as a former U.S. Marine, Amir Mirzaei Hekmati received special training and served at U.S. military bases in Iraq and Afghanistan before heading to Iran for his alleged intelligence mission. The radio report did not say when the verdict was issued. Under Iranian law, he has 20 days to appeal.
The 28-year-old former military translator was born in Arizona and graduated from high school in Michigan. His family is of Iranian origin. His father, a professor at a community college in Flint, Michigan, has said his son is not a CIA spy and was visiting his grandmothers in Iran when he was arrested.
His trial took place as the U.S. announced new, tougher sanctions against Iran over its nuclear program, which Washington believes Tehran is using to develop a possible atomic weapons capability.
Iran, which says it only seeks nuclear reactors for energy and research, has sharply increased its threats and military posturing against stronger pressures, including the U.S. sanctions targeting Iran's Central Bank in attempts to complicate its ability to sell oil.
The U.S. State Department has demanded Hekmati's release.
The court convicted him of working with a hostile country, belonging to the CIA and trying to accuse Iran of involvement in terrorism, Monday's report said.
In its ruling, a branch of Tehran Revolutionary Court described Hekmati as a mohareb, an Islamic term that means a fighter against God, and a mofsed, or one who spreads corruption on earth. Both terms appear frequently in Iranian court rulings.
In a closed court hearing in late December, the prosecution asked for the death penalty for Hekmati.
The U.S. government has called on Iranian authorities to grant Swiss diplomats access to him in prison. The Swiss government represents U.S. interests in Iran because the two countries don't have diplomatic relations.
Hekmati is a dual U.S.-Iranian national. Iran considers him an Iranian since the country's law does not recognize dual citizenship.
His father, Ali Hekmati, and family friend Muna Jondy, an attorney who has been speaking on behalf of the family, did not immediately respond to emails and phone messages left at their offices before business hours Monday morning.
Similar cases against Americans accused of spying have heightened tensions throughout the years-long standoff over Iran's nuclear program.
Iran arrested three Americans in July 2009 along the border with Iraq and accused them of espionage, though the Americans said they were just hiking in the scenic and relatively peaceful Kurdish region of northern Iraq.
One of them was released after a year in prison, and the other two were freed in September in deals involving bail payments that were brokered by the Gulf sultanate of Oman, which has good relations with Iran and the U.S.
On Dec. 18, Iran's state TV broadcast video of Hekmati delivering a purported confession in which he said he was part of a plot to infiltrate Iran's Intelligence Ministry.
In a statement released the same day, the Intelligence Ministry said its agents identified Hekmati before his arrival in Iran, at Bagram Air Field in neighboring Afghanistan. Bagram is the main base for American and other international forces outside Kabul, the Afghan capital.
It is not clear exactly when he was arrested. Iranian news reports have said he was detained in late August or early September.
Hekmati's father, Ali, said in a December interview with The Associated Press, that his son was a former Arabic translator in the U.S. Marines who entered Iran about four months earlier to visit his grandmothers.
At the time, he was working in Qatar as a contractor for a company "that served the Marines," his father said, without providing more specific details.
