DUBAI (AP) — Nuclear talks between Iran and the United States will take place Friday in Oman, the Iranian foreign minister said, as tensions between the countries remain high following Tehran's bloody crackdown on nationwide protests last month.

The announcement by Iranian Foreign Minister Abbas Araghchi on Wednesday came after hours of indications that the anticipated talks were faltering over changes in the format and content of the talks.

”I’m grateful to our Omani brothers for making all necessary arrangements,” Araghchi wrote on X on Wednesday evening.

Earlier Wednesday, a regional official said Iran was seeking a “different” type of meeting than that what had been proposed by Turkey, one focused exclusively on the issue of Iran’s nuclear program, with participation limited to Iran and the United States. The official spoke on condition of anonymity because they were not authorized to brief the media.

The Trump administration confirmed the U.S. will take part in high-level talks with Iran in Oman instead of Turkey as originally planned, according to a White House official.

The official, who was not authorized to comment publicly and spoke on the condition of anonymity, said that several Arab and Muslim leaders urged the Trump administration on Wednesday not to walk away from talks even as Iranian officials pressed to narrow the scope of talks and change the venue for the negotiations.

The official added that the White House remains “very skeptical” that the talks will be successful but have agreed to go along with the change in plans out of respect for allies in the region.

Tensions between the countries spiked after U.S. President Donald Trump suggested the U.S. might use force against Iran in response to the crackdown on protesters. Trump also has been pushing Tehran for a deal to constrain its nuclear program.

Iran’s reformist President Masoud Pezeshkian on Tuesday said he had instructed the foreign minister to “pursue fair and equitable negotiations” with the U.S., in the first clear sign from Tehran it wants to try to negotiate. That signaled the move is supported by Supreme Leader Ayatollah Ali Khamenei, who has the final say on all matters of state and previously dismissed any negotiations.

U.S. Secretary of State Marco Rubio said the U.S. hoped to discuss a number of concerns beyond the nuclear issue, including discussions on Iran’s ballistic missiles, support for proxy networks across the region and the “treatment of their own people.”

“The leadership of Iran at the clerical level does not reflect the people of Iran. I know of no other country where there’s a bigger difference between the people who lead the country and the people who live there,” he told reporters.

Vice President JD Vance told “The Megyn Kelly Show” that diplomatic talks with Iran are challenging because of Tehran’s political system, overseen by Khamenei.

“It’s a very weird country to conduct diplomacy with when you can’t even talk to the person who’s in charge of the country. That makes all of this much more complicated, and it makes the whole situation much more absurd,” Vance said, noting that Trump could speak directly by phone with the leaders of Russia, China or North Korea.

Vance said Trump’s bottom line is that Iran cannot be allowed to develop a nuclear weapon, asserting that other states in the region would quickly do the same.

Iran long has insisted its nuclear program is peaceful. However, Iranian officials in recent years have increasingly threatened to pursue the bomb.

Vance said he believed Trump would work to “accomplish what he can through non-military means. And if he feels like the military is the only option, then he’s ultimately going to choose that option.”

On Tuesday, a U.S. Navy fighter jet shot down an Iranian drone that approached an American aircraft carrier. Iranian fast boats from its paramilitary Revolutionary Guard also tried to stop a U.S.-flagged ship in the Strait of Hormuz, the narrow mouth of the Persian Gulf, the Navy said.

Iran did not immediately acknowledge either incident, which strained but apparently did not derail hopes for talks with the U.S.

On Wednesday, Iranian military chiefs visited a missile base in an attempt to highlight its military readiness after a 12-day war with Israel in June devastated Iran’s air defenses. The base holds the Khorramshahr missile, which has a range of more than 2,000 kilometers (1,250 miles) and was launched towards Israel during the war last year.

Also Wednesday, Turkish President Recep Tayyip Erdogan reiterated Turkey’s opposition to foreign intervention in neighboring Iran, calling for the resolution of issues through dialogue.

Turkey has been urgently working for the past week to bring the U.S. and Iran to the negotiating table, and was previously expected to host the talks.

“We believe that external interventions involving our neighbor Iran would pose significant risks for the entire region,” Erdogan said during a visit to Cairo. “Resolving issues with Iran, including the nuclear file, through diplomatic means is the most appropriate approach.”
