ROME >> Iran and the United States will begin having experts meet to discuss details of a possible deal over Tehran’s rapidly advancing nuclear program, the top Iranian diplomat said Saturday after a second round of negotiations in Rome.

The comments by Iranian Foreign Minister Abbas Araghchi, who met with U.S. Mideast envoy Steve Witkoff for several hours, suggest movement in the talks. The experts will meet in Oman before Araghchi and Witkoff meet again in Oman on April 26, Araghchi said.

There was no immediate readout from the U.S. side after the meeting at the Omani Embassy in Rome’s Camilluccia neighborhood. President Donald Trump has been pushing for a rapid deal with Iran while threatening military action against it.

“The talks were held in a constructive environment and I can say that is moving forward,” Araghchi told Iranian state television. “I hope that we will be in a better position after the technical talks.”

He added: “This time, we succeeded to reach a better understanding about a sort of principles and aims.”

Iranian officials described the talks as indirect, like those last weekend in Muscat, Oman, with Omani Foreign Minister Badr al-Busaidi shuttling between them in different rooms.

“These talks are gaining momentum and now even the unlikely is possible,” al-Busaidi said on X.

In a separate post, Oman’s Foreign Ministry said the sides agreed to keep talking to seek a deal that ensures Iran is “completely free of nuclear weapons and sanctions, and maintaining its ability to develop peaceful nuclear energy.”

That talks are even happening represents a historic moment, given the decades of enmity between the two countries since the 1979 Islamic Revolution and the U.S. Embassy hostage crisis. Trump, in his first term, unilaterally withdrew from Iran’s nuclear deal with world powers in 2018, setting off years of attacks and negotiations that failed to restore the accord that drastically limited Tehran’s enrichment of uranium in exchange for the lifting of economic sanctions.

At risk is a possible American or Israeli military strike on Iran’s nuclear sites, or the Iranians following through on their threats to pursue an atomic weapon. Meanwhile, tensions in the Middle East have spiked over the Israel-Hamas war in the Gaza and after U.S. airstrikes targeting Yemen’s Iranian-backed Houthi rebels killed more than 70 people and wounded dozens more.

“I’m for stopping Iran, very simply, from having a nuclear weapon,” Trump said Friday. “I want Iran to be great and prosperous and terrific.”

Before the Iran talks started, Witkoff met in Rome with Rafael Mariano Grossi, head of the International Atomic Energy Agency, according to a person familiar with the meeting who spoke on condition of anonymity to share details that were not made public.

The U.N. nuclear watchdog agency would likely be key in verifying compliance by Iran should a deal be reached, as it did with the 2015 accord Iran reached with world powers.

In a flurry of gatherings, Grossi also met with Italian Foreign Minister Antonio Tajani, who sat down with Araghchi before the U.S.-Iran talks.

A diplomatic deal “is built patiently, day after day, with dialogue and mutual respect,” Tajani said in a statement.

Both men have been traveling in recent days. Witkoff had been in Paris for talks about Ukraine as Russia’s full-scale war there grinds on. Witkoff also met in the French capital with Israeli Prime Minister Benjamin Netanyahu’s strategic affairs minister, Ron Dermer, and Mossad chief David Barnea.

Dermer was in Rome on Saturday and spotted at the same hotel where Witkoff is staying. It was unclear whether that was a coincidence, and there was no indication Dermer was part of the Iran talks.

Araghchi in recent days paid a visit to Moscow, where he met with officials, including Russian President Vladimir Putin.

Russia, one of the world powers involved in Tehran’s 2015 nuclear deal, could be a key participant in any future deal reached between Tehran and Washington. Analysts suggest Moscow could potentially take custody of Iran’s uranium enriched to 60% purity — a short, technical step away from weapons-grade levels of 90%.

Oman’s capital, Muscat, hosted the first round of negotiations between Araghchi and Witkoff last weekend, which saw the two men meet face to face after indirect talks. Oman, a sultanate on the eastern edge of the Arabian Peninsula, has long served as an interlocutor between Iran and the West.

Ahead of the talks, however, Iran seized on comments by Witkoff first suggesting Iran could enrich uranium at 3.67%, then later saying that all enrichment must stop.
