Tehran has accused the US and Saudi Arabia of involvement in the disappearance of a scientist though to be linked to Iran's nuclear programme.

Washington denies it has anything to do with Shahram Amiri, who vanished during a pilgrimage to Saudi Arabia.

Al Jazeera's Nazanine Moshiri reports from Tehran, where many suspect that Amiri may have defected.
