A senior Obama administration official says the nuclear deal with Iran does not include recognition of Iran's right to enrich uranium.
That had been a sticking point in the negotiations between Iran and six world powers, including the United States.
The official says the deal includes an agreement that Iran will halt progress on its nuclear program, including a plutonium reactor at the Arak facility. The deal also calls on Iran to neutralize its 20 percent enriched uranium stockpiles.
Tehran has also agreed to intrusive inspections under the terms of the deal.
The official was not authorized to discuss the terms of the agreement by name and insisted on anonymity.
The French foreign minister says Iran and six world powers have reached a first-stage agreement on curbing Iran's nuclear program in return for sanctions relief.
Laurent Fabius gave no details as he left a meeting of foreign ministers early Sunday in a fifth day of talks.
A formal announcement was expected soon.
