Iran and US Reportedly Receive Plan to End War and Open Hormuz Strait

Iran and the United States have accepted a plan to end hostilities that could take effect on Monday and reopen the Strait of Hormuz, a source familiar with the proposal said on Monday.

"A framework for ending hostilities has been drafted by Pakistan and exchanged with Iran and the US overnight," said the source, who outlined a two-stage approach with an immediate ceasefire followed by a comprehensive agreement.

"All elements need to be agreed today," the source said, adding that the initial understanding would be drafted as a memorandum of understanding completed electronically through Pakistan, the only channel of communication in the talks, Al Arabiya reported from Reuters (6/4).

Previously, Axios first reported on Sunday that Washington, Tehran and regional mediators were discussing a potential 45-day ceasefire as part of a two-phase deal that could lead to a permanent end to the war, citing US, Israeli and regional sources.

The source told Reuters that the Chief of the Pakistan Army, Field Marshal Asim Munir, had been in contact "all night" with US Vice President JD Vance, Special Envoy Steve Witkoff, and Iranian Foreign Minister Abbas Araghchi.

Based on the proposal, a ceasefire will take effect immediately, reopening the Strait of Hormuz, with a time of 15-20 days to complete a broader agreement.

The agreement, which for now is called the "Islamabad Agreement," will include a regional framework for the strait, with the last face-to-face talks in Islamabad.

There was no immediate response from the US. Meanwhile, Pakistan's Foreign Ministry spokesman, Tahir Andrabi, declined to comment.

Meanwhile, a senior Iranian official told Reuters on Monday that the Iranian Mullah State would not reopen the Strait of Hormuz in return for a "temporary ceasefire," adding that Tehran considered Washington less prepared for a permanent ceasefire.

The official confirmed Iran had received Pakistan's proposal for an immediate ceasefire and was reviewing it, adding Tehran was not under pressure to accept a deadline and make a decision.

Iranian officials have previously told Reuters that Tehran is seeking a permanent ceasefire with assurances that it will not be attacked again by the US and Israel.

They said Iran had received messages from mediators including Pakistan, Turkey, and Egypt.

The final agreement is expected to include Iran's commitment not to pursue nuclear weapons in return for the lifting of sanctions and the release of frozen assets, the source said.

Meanwhile, two Pakistani sources said Iran had not made any commitments despite increased civilian and military outreach efforts.

"Iran has not responded," one of the sources said, adding that a proposal backed by Pakistan, China and the United States for a temporary ceasefire has not produced commitments so far.

There was no immediate response from Chinese officials to a request for comment.

The latest diplomatic effort comes amid rising hostilities that have raised concerns of disruption to shipping through the Strait of Hormuz, a vital route for global oil supplies.

It is known that US President Donald Trump in recent days has publicly urged that the conflict be immediately ended, warning of the consequences if a ceasefire is not reached in a short time.

The conflict has increased volatility in the energy market, with traders closely monitoring any developments that could affect flows through the strait.
