The Iranian government says it has evidence that one of its nuclear scientists was abducted and is being held in the US against his will.
Shahram Amiri disappeared a year ago while on a pilgrimage in Saudi Arabia.
Iranian television broadcast a video purporting to show the scientist saying he was kidnapped and is now living in Arizona.
Hours later, another video posted on YouTube appeared to show Mr Amiri saying he was happy in the US.
In the video shown on the Islamic Republic of Iran Broadcasting network, the man says he was forced to say he defected with a laptop full of evidence about Iran's nuclear secrets and that he was being used to put pressure on Iran.
The video showed a man wearing headphones and talking to his webcam.
He says he was in the Saudi city of Medina as part of a Muslim pilgrimage when Saudi intelligence officers drugged and kidnapped him.
"When I became conscious, I found myself in a plane on the way to the US," he said.
"Since I was abducted and brought to the US I was heavily tortured and pressured by US intelligence."
Neither the US nor the Saudi Arabian governments have made any comment on the allegations that he was abducted and taken to the US.
In March US news channel ABC ran a report quoting unnamed US officials that said Mr Amiri had defected and was helping the US compile intelligence on Iran's nuclear weapons programme.
They suggested that he had given them valuable information about the Iranian nuclear programme, including the recently revealed centrifuge enrichment plant outside the city of Qom.
The secret plant was revealed in September last year, just days before a meeting in Geneva between Iran and the permanent five members of the UN Security Council.
The US and its allies believe Iran is trying to acquire a nuclear weapon, but Tehran denies the charge.
