Al-Jazeera Video: Iran scientist alleges US torture

"The Iranian scientist who says he was kidnapped by US agents over information on Iran's nuclear programme, has returned to his home country.

Shahram Amiri claims he was drugged and abducted by US agents during a Hajj pilgrimmage to Saudi Arabia and flown to the United States against his will.

He also says he was tortured physically and psychologically during the 14 months he was held for interrogation in the US.

But that contradicts an earlier Youtube posting in which he said he was in the US of his own free will.
