TEHRAN/BAGHDAD – Iran has confirmed that Muscat, the capital of Oman, will remain the venue for the second round of "indirect" negotiations between Tehran and Washington.

"Following consultations, it was decided that Muscat continues to be the host of the second round of the negotiations, which are scheduled to be held on Saturday," the semi-official Mehr news agency quoted Iranian Foreign Ministry spokesman Esmaeil Baghaei as saying on Tuesday.

In the first round of Muscat talks on Saturday, Iranian Foreign Minister Seyed Abbas Araghchi engaged in "indirect" discussions with US Special Envoy to the Middle East Steve Witkoff, facilitated by Omani Foreign Minister Sayyid Badr bin Hamad bin Hamood Albusaidi.

These talks focused on Iran's nuclear program and the potential removal of US sanctions.

The talks in Muscat followed US President Donald Trump's statement in early March that he had sent a letter to Iranian leaders, delivered through the United Arab Emirates, proposing negotiations on Iran's nuclear program. Iran later agreed on indirect talks.

Iran signed a nuclear deal in July 2015 with six major countries – Britain, China, France, Germany, Russia and the US. Under the deal, Iran agreed to limit its nuclear activities in exchange for sanctions relief.

However, Trump unilaterally pulled his country out of the deal in May 2018 during his first term, and reimposed sanctions on Iran, prompting Tehran to scale back its commitments under the deal. Since then, efforts to revive the nuclear agreement have made little progress.

Meanwhile, the Iranian foreign minister held separate phone conversations with his Saudi and Iraqi counterparts exchanging views on the Oman-mediated "indirect" talks between Tehran and Washington.

Araghchi and his Saudi counterpart also discussed bilateral relations as well as latest regional and international developments, the statement added.

In talks with Iraqi Foreign Minister Fuad Hussein, Araghchi briefed Hussein on the latest developments in the Iran-US negotiations, saying that the talks as proceeding "well".

The Iraqi Foreign Ministry said in a statement that Hussein affirmed Iraq's support for all effort that contributes to enhancing regional security and stability.
