Iran and the U.S. began negotiations in Oman on Saturday over Tehran’s advancing nuclear program, and the talks will likely depend on the Islamic Republic’s enrichment of uranium.

According to Iranian state media, the talks began on Saturday in Oman’s capital of Muscat. But Iranian Foreign Minister Abbas Araghchi and U.S. Mideast envoy Steve Witkoff offered no immediate details on the talks.

Araghchi arrived on Friday in Oman and met with Omani Foreign Minister Badr al-Busaidi, who had mediated the two earlier rounds of talks in Muscat and Rome. Araghchi was seen heading to the talks late Saturday morning.

“There are some people that want to make a different kind of a deal — a much nastier deal — and I don’t want that to happen to Iran if we can avoid it,” he added.
