A former Iranian nuclear negotiator, who was detained last week for "security reasons", was released on bail today, Mehr News Agency reported.
Hossein Mousavian, considered a moderate conservative by analysts, was a member of Iran's nuclear negotiating team with the European Union and was head of the foreign policy committee on the Supreme National Security Council.
Like most other members of the team, he was replaced by more hardline officials when President Mahmoud Ahmadinejad took office in 2005.
Mehr News Agency quoted what it called an informed source as saying Mr Mousavian "who had been arrested at his home last week was freed this evening". The agency said he was freed on bail.
Iran's ISNA news agency earlier yesterday quoted a judiciary spokesman as saying Mr Mousavian was expected to be released once he posted bail.
When he was arrested, a news agency said he was detained for "security reasons". Documents and his personal computer were still being held by the authorities as the inquiry continued, Mehr reported.
