Quoting two regional sources and a US official, the report said the proposed agreement is designed to reduce tensions after months of military confrontation and create space for fresh negotiations over Iran’s nuclear programme.

Under the draft arrangement, Oman and Iran would implement a 60-day temporary navigation framework in the Strait of Hormuz, with the possibility of extending the agreement.

The proposal envisions inbound vessels entering the Gulf through a northern shipping lane in Iranian waters, while outbound traffic would travel via a southern route in Omani waters in coordination with Iran.

The temporary arrangement would not impose any transit charges or tolls on commercial shipping.

The plan also includes a joint effort to remove naval mines from the central shipping lane within 30 days.

Once the operation is completed, the central channel could be reopened for two-way maritime traffic under a broader long-term agreement to be negotiated between Oman and Iran.

The diplomatic initiative follows US President Donald Trump’s decision to delay a large-scale military campaign against Iran in favour of giving diplomacy another opportunity.

While pausing further escalation, Trump has warned that Washington remains prepared to launch major military action if negotiations collapse.

The report said the talks have involved officials from Oman, Qatar, Pakistan and Saudi Arabia, with the White House playing a central role in the negotiations.

Trump’s special envoy Steve Witkoff has reportedly held several recent conversations with Iranian Foreign Minister Abbas Araghchi and Omani Foreign Minister Badr Al Busaidi.

According to regional sources, Araghchi endorsed the proposed arrangement in principle over the weekend, subject to approval by Iran’s Supreme Leader Mojtaba Khamenei and the Supreme National Security Council.

A US official and a regional source told Axios that Iran’s leadership completed the approval process on Tuesday.

Speaking earlier in the day, US Secretary of State Marco Rubio said discussions over safe passage through key international waterways had not yet been finalised but expressed hope that an agreement would be reached “very shortly.”

The renewed diplomatic push follows months of hostilities between Washington and Tehran, which began in February after joint US-Israeli strikes targeted the Iranian capital.

Iran responded with missile and drone attacks targeting Gulf states hosting American military assets.

Although both sides agreed to a ceasefire in April and later signed a Pakistan-mediated memorandum of understanding in June aimed at ending hostilities, the agreement collapsed last month.

The renewed fighting lasted nearly two weeks before Trump ordered a halt to US bombardments amid renewed diplomatic efforts to revive negotiations.
