The Associated Press quoted US officials as saying that Washington plans to soften its tone over the enrichment facility in a trade-off that would allow Iran to run several hundred of centrifuge machines at its Fordo facility, according to Western officials familiar with details of negotiations now underway.
"In return, Iran would be required to scale back the number of centrifuges it runs at its Natanz facility and accept other restrictions on nuclear-related work," the AP report said.
The official spoke only on condition of anonymity because they were not authorized to discuss details of the sensitive negotiations as the latest round of talks began between US Secretary of State John Kerry and Iranian Foreign Minister Mohammed Javad Zarif.
AP also quoted Washington officials as stressing that the potential compromise on Fordo is just one of several options on a menu of highly technical equations being discussed in the talks.
