Iran's Foreign Minister Abbas Araghchi says that he, via Oman's Foreign Minister on a visit to Tehran, has received "the basics of an American agreement".
The White House Press Secretary Karoline Leavitt said on Saturday that it was in Tehran's "best interest to accept" the agreement and added:
President Trump has made it clear that Iran will never be able to acquire" nuclear weapons.
According to Leavitt, a "detailed and acceptable" proposal has been sent to Iran by the US special envoy Steve Witkoff.
The American proposal "will be responded to in a suitable manner in line with principles, national interests, and the rights of the Iranian people", writes Araghchi on X.
Has enriched more uranium
The information comes just hours after a report from the UN's atomic energy agency IAEA was published. It states that Iran has accelerated its production of uranium enriched to near the level for developing nuclear weapons.
On Sunday, Iran warns European countries against "misusing" the UN report "to promote their political goals", reports AFP.
Iran has for years denied that the country wants to develop nuclear weapons. Tehran claims that the purpose of its nuclear energy program is peaceful.
American intelligence services estimate that Iran does not yet have a nuclear weapons program, but that the country has positioned itself to start one if it wanted to.
Oman mediates
Iran and the US have been holding nuclear energy talks since April 12. Oman is acting as an intermediary in the talks. It is the highest level between the countries since a previous agreement between Iran and the Western world from 2015, the so-called JCPOA, fell apart in 2018. This happened when the US President Donald Trump backed out of it during his first term.
The JCPOA agreement aims to prevent Iran from developing nuclear weapons by providing insight into the country's nuclear energy program in exchange for easing sanctions.
