Iran has hinted it might allow diplomats visiting Tehran for this week's Non-Aligned Movement (NAM) summit to visit a military installation that UN inspectors suspect has been used for nuclear military experiments.
Iran says Parchin, a huge complex southeast of Tehran, is a conventional military facility and has dismissed the allegations.
Deputy Foreign Minister Mohammad Mehdi Akhoundzadeh was quoted by the government-linked news agency Young Journalists Club as saying, "Such a visit [to Parchin] is not customary in such meetings.... However at the discretion of the authorities, Iran would be ready for such a visit."
Iran is hosting the NAM summit, which ends on August 31.
The tentative offer was made just three days after the UN's International Atomic Energy Agency again requested access to Parchin for its inspectors at a meeting in Vienna.
