Iran and the United States have received a plan to end hostilities that could come into effect on Monday and reopen the Strait of ⁠Hormuz, a source aware of the proposals said on Monday.

A framework to end hostilities has been put together by Pakistan and exchanged with Iran and the United States overnight, the source said, outlining a two-tier approach with an immediate ceasefire followed by a comprehensive agreement.

"All elements need to be agreed today," the source said, adding the initial understanding would be structured as a memorandum of understanding finalised electronically through Pakistan, the sole communication channel in the talks.

Axios first reported on Sunday that the United States, Iran 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 said Pakistan's army chief, Field Marshal Asim Munir, had been in contact "all night long" with US Vice President JD Vance, special envoy Steve Witkoff ⁠and Iranian Foreign Minister Abbas Araqchi.

Under the proposal, a ceasefire would take effect immediately, reopening the Strait of Hormuz, with 15 to 20 days to finalise a broader settlement. The deal, tentatively dubbed the "Islamabad Accord," would include a regional framework for the strait, with final in-person talks in the Pakistani capital.

Iranian officials have said Tehran is seeking a permanent ceasefire with guarantees they will not be attacked again by the United States and Israel. They have said Iran has received messages from mediators including Pakistan, Turkiye and Egypt.

The final agreement is expected to include Iranian commitments not to pursue nuclear weapons in exchange for sanctions relief and the release of frozen assets, the source said.

Two Pakistani sources said Iran had yet to commit despite intensified civilian and military outreach.

"Iran has not responded yet," one source ⁠said, adding proposals backed by Pakistan, China and the United States for a temporary ceasefire have drawn no commitment so far.

There was no immediate response from Chinese officials to requests for comment. (Reuters)
