A senior Obama administration official says the U.S. and its five allies trying to stop Iran's suspected nuclear weapons program plan to tell Iran on Thursday that it must provide within a matter of weeks unfettered access to Iran's previously secret enrichment facility.
The official says that the allies also will present a so-called transparency package covering all of Iran's nuclear activities across the country.
The official says that the allies will not give Iran a specific deadline to provide the information about its overall program.
The meeting with Iran is scheduled for Thursday in Geneva.
