Iran's Intelligence Ministry says its agents have arrested a person of Iranian origin suspected of spying for the United States.
A ministry statement broadcast on state TV Saturday said Iran's secret services identified the suspect at Bagram Air Field in Afghanistan and detained the individual after crossing into Iran.
The report did not elaborate.
Bagram is the main base for American and other international forces outside Kabul.
State TV alleged the suspect, who was not identified, received special training and sought to infiltrate Iran's secret services and funnel false information to deceive Iranian intelligence.
Tehran periodically announces the capture or execution of alleged US or Israeli spies, and often no further information is released.
Earlier Saturday, a European intelligence source claimed Iran stunned Western intelligence agencies when it managed to "blind a CIA spy satellite
by aiming a laser burst quite accurately," in a never before reported incident.
According to an article in The Christian Science Monitor, this unreported incident might suggest that the Iranians have successively gained access to jamming technology,
allowing them to track unmanned aerial vehicle navigation capabilities.
Former US Ambassador to the United Nations John Bolton
told Fox News on Sunday that such an option is possible.
Some reports have said Russia sold (Iran) a very sophisticated jamming system a short time ago. Now, our military says that is not true, it came down because of a malfunction. I certainly hope that's right because if the Russians have provided Iran with sophisticated jamming equipment it means a lot else is at risk too," said Bolton.
He added that Congress should be quite concerned if Iran is in possession of jamming technology that can bring down missiles, planes and communications and guidance systems "for a whole range of our weapon systems."
Meanwhile, Iran's foreign minister said on Saturday that his country deliberately delayed its announcement of the capture of an American surveillance drone to test US reaction.
Ali Akbar Salehi is quoted by the official IRNA news agency as saying Saturday that Iran's armed forces intercepted and brought down the pilotless aircraft without any foreign assistance.
On Friday US offcials said they believe the American stealth drone displayed in Iran had crashed and broke into pieces and was put back together by Iranians to make it seem it was not damaged by the crash, reported The Wall Street Journal.
