Iran's nuclear negotiators will return to Tehran from Vienna after days of indirect talks on reviving a 2015 deal with Washington and other world powers, the state news agency IRNA reported on Monday.
Consultations would continue with the coordinator of the talks and the other parties, IRNA added.
In 2018, then US President Donald Trump ditched the deal and reimposed harsh sanctions. In response, Tehran - which says its nuclear program is for power generation and other peaceful purposes - breached the agreement in several ways, including rebuilding stocks of enriched uranium.
Iran's Foreign Minister Hossein Amirabdollahian said on Sunday that the nuclear pact depended on Washington's flexibility.
Indirect talks between Iran and the United States to save the 2015 pact resumed in Vienna last Thursday.
