Dubai, Apr 17 (AP) Iran confirmed Wednesday that the next round of nuclear talks with the United States this weekend will be held in Rome after earlier confusion over where the negotiations would be held.

The announcement by Iranian state television came as Iran’s President Masoud Pezeshkian formally approved the resignation of one of his vice presidents who served as Tehran’s key negotiator in its 2015 nuclear deal with world powers.

The head of the United Nations’ nuclear watchdog, Rafael Mariano Grossi of the International Atomic Energy Agency, also arrived in the Islamic Republic on Wednesday. His talks may include negotiations over just what access the IAEA inspectors can get under any proposed deal.

The state TV announcement said Oman will again mediate the talks on Saturday in Rome. Oman’s foreign minister served as an interlocutor between the two sides at talks last weekend in Muscat, the sultanate’s capital.

Officials initially on Monday identified Rome as hosting the negotiations, only for Iran to insist early Tuesday they would return to Oman. American officials so far haven’t said publicly where the talks will be held, though Trump did call Oman’s Sultan Haitham bin Tariq on Tuesday, while the ruler was on a trip to the Netherlands.

The stakes of the negotiations couldn’t be higher for the two nations closing in on half a century of enmity. U.S. President Donald Trump repeatedly has threatened to unleash airstrikes targeting Iran’s nuclear program if a deal isn’t reached. Iranian officials increasingly warn that they could pursue a nuclear weapon with their stockpile of uranium enriched to near weapons-grade levels.

Pezeshkian praises former vice president while acknowledging his resignation The former vice president, Mohammad Javad Zarif, served as a key supporter of Pezeshkian in his election last year but drew criticism from hard-liners within Iran’s Shiite theocracy, who long have alleged Zarif gave away too much in negotiations.

In March, Zarif tendered his resignation to Pezeshkian. However, the president did not immediately respond to the letter. Zarif has used resignation announcements in the past in his political career as leverage, including in a dispute last year over the composition of Pezeshkian’s Cabinet. The president had rejected that resignation.

But on late Tuesday, a statement from the presidency said Pezeshkian wrote Zarif a letter praising him but accepting his resignation.

“Pezeshkian emphasized that due to certain issues, his administration can no longer benefit from Zarif’s valuable knowledge and expertise,” a statement from the presidency said.

The president in a decree appointed Mohsen Ismaili, 59, to be his new vice president for strategic affairs. In Iran’s political system, the president has multiple vice presidents. Ismaili is known as a political moderate and a legal expert. (AP) MNK MNK
