A U.N. inspectors' team is in Tehran in a renewed effort to engage Iran and secure access to a site linked to suspected nuclear activity.

Iran's official IRNA news agency said Thursday the seven-member team - headed by Herman Nackaerts, a deputy director general of the International Atomic Energy Agency - would meet with Iranian nuclear officials.

The report says the two sides will try to reach a framework for restarting talks on Iran's nuclear program.

The IAEA has demanded for over a year to visit Parchin military site, which the agency says could have been used for experiments related to nuclear weapons. Iran insists the site is only a conventional military facility.

The West suspects Iran is trying to make a nuclear weapon. Tehran denies the charge.
