DUBAI, United Arab Emirates (AP) — The United States and Iran on Monday separately announced they will send delegations to Qatar this week, though Tehran insisted it has not agreed to meet with the U.S. “at any level” after attacks across the Persian Gulf over the weekend challenged negotiations to end the war.

U.S. President Donald Trump said the Islamic Republic had requested a meeting with U.S. counterparts and that they planned to convene today in Doha, Qatar.

But one of Iran’s senior negotiators denied talks had been scheduled. And the spokesman for Iran’s Foreign Ministry said Tehran was sending its delegation to Qatar, a key mediator in the negotiations, to discuss terms of the interim deal without involving the U.S.

The U.S. president has tried to preserve a fragile interim deal, but hostilities mounted in recent days in the Strait of Hormuz, through which a fifth of the world’s oil had been shipped before war began. After four days of trading strikes, both sides appeared to pause their attacks Monday.

The U.S. and Iran agreed to an interim deal earlier this month that calls for Tehran to dilute its stockpile of enriched uranium. It also waives U.S.-backed sanctions on the country, opens the Strait of Hormuz and gives each side 60 days to hammer out broader agreements.

After Trump said Monday morning on social media that the U.S. and Iran planned to meet, White House press secretary Karoline Leavitt told Fox News’ “Fox & Friends” that special envoy Steve Witkoff and Jared Kushner, the president’s son-in-law, were flying to Qatar.

Pakistan, also a key mediator, had said talks between Iran and the U.S. would resume today.

But Kazem Gharibabadi, a senior negotiator for Iran, said in comments published by Iranian state media that no talks had been confirmed. And Esmail Baghaei, spokesman for Iran’s Foreign Ministry, said that its delegation was traveling to Qatar this week to discuss the planned release of frozen Iranian assets and other issues related to the deal.

“There are no negotiation meetings with the U.S. side at any level scheduled in the coming days,” Baghaei said. “The fact that U.S. representatives are traveling to Qatar has no connection with the visit of the Iranian delegation.”

During the war that began Feb. 28, Iran’s attacks and threats stopped cargo ships and tankers from moving through the Strait of Hormuz, creating a global energy crisis.

In recent days, Iran has twice attacked vessels in the strait — including a tanker filled with Qatari crude — following efforts to open Oman’s territorial waters to both inbound and outbound traffic from the Persian Gulf.

The attacks drew retaliatory American airstrikes and raised concerns that negotiations to reach a formal end to the war could be disrupted. Iran launched drone and missile attacks targeting Bahrain and Kuwait on Sunday.

The strait has long been considered an international waterway despite its location in Iran and Oman’s territorial waters.

The Trump administration was operating Monday on the understanding that the U.S. and Iran are standing down after the recent back-and-forth strikes and that vessels can move freely through the Strait of Hormuz, said a U.S. official who requested anonymity to discuss the sensitive negotiations.

The U.S. official also said that Qatar planned to release $6 billion in frozen Iranian assets that would be used to purchase U.S. food products for the Iranian people.

Iranian President Masoud Pezeshkian had announced the expected release of funds earlier Monday in comments published by the state-run IRNA news agency. He called it “a great victory for the Iranian people.”

Pezeshkian, a reformist within Iran’s theocracy, is the highest-ranking official within Iran to reference the release of the funds held by Qatar, a key mediator along with Pakistan in the negotiations.
