An Iranian diplomat who was freed last week after being abducted in Iraq in February has said he was repeatedly tortured by his captors, including CIA agents.
The US military in Iraq said the coalition forces had not been involved in the abduction or any torture of Jalal Sharafi, the second secretary at Iran's embassy in Baghdad.
Mr Sharafi told Iranian media that he had been taken from his car by men in Iraqi army uniforms and that the CIA had interrogated him on his country's role in Iraq.
His comments follow the release during the week of 15 British troops from Iran, who say they were mistreated.
Iran denies mistreating British navy personnel
An advisor to Iranian President Mahmoud Ahmadinejad has denied that the British sailors and marines seized by Iran had been mistreated, saying they had made such claims under pressure from their superiors.
Ali Akbar Javanfekr said: 'The mistreatment of the sailors is a lie.
'The British authorities should know that they cannot keep hiding the truth from the British people.
'We envisioned that the 15 sailors would be subjected to pressure by British security and intelligence forces.
'For that reason, President Ahmadinejad asked Prime Minister Tony Blair not to put pressure on the sailors for having told the truth, but (he) did not hear this humanitarian appeal.
'By dictating certain statements made by the freed troops, the British authorities are seeking to improve their situation and diminish the pressure of British public opinion.'
