A newspaper is reporting that the CIA paid an Iranian nuclear scientist $5 million to provide intelligence on Iran's nuclear programme.
The scientist, Shahram Amiri, returned to Iran on Wednesday to a hero's welcome after claiming he was abducted by US agents and then offered $50 million to stay in the US The US says Amiri was a willing defector who changed his mind and asked to go back to Iran.
The Washington Post said in its online edition late on Wednesday that Amiri had been working for the CIA for more than a year. It said he was paid $5 million out of a secret program aimed at inducing scientists and others with information on Iran's nuclear program to defect.
Amiri says he had no classified information.
