Iran, U.S. receive plan to end hostilities, immediate ceasefire; source says

April 6 (Reuters) – Iran and the United States have received a plan to end hostilities that could come into force on Monday and reopen the Strait of Hormuz, a source with knowledge of the proposals said on Monday.

A framework to end hostilities was created by Pakistan and shared with Iran and the US overnight, the source said, outlining a two-stage approach that includes an immediate ceasefire followed by a comprehensive agreement.

“All elements need to be agreed upon today,” the source said, adding that the initial memorandum would be structured as a memorandum of understanding concluded electronically through Pakistan, the only communication channel for the negotiations.

Axios first reported 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 U.S., Israeli and regional sources.

The source told Reuters that Pakistani army chief Field Marshal Asim Munir was in contact “all night long” with US Vice President JD ⁠Vance, special envoy Steve Witkoff and Iranian Foreign Minister Abbas Araqchi.

According to the proposal, the ceasefire would come into effect immediately and the Strait of Hormuz would be reopened, allowing 15-20 days to finalize a broader solution. The agreement, tentatively called the “Islamabad Agreement”, will include a regional framework for the strait, with final face-to-face talks in Islamabad.

There was no immediate response from US and Iranian officials. Pakistani foreign affairs spokesman Tahir Andrabi declined to comment.

Iranian officials have previously told Reuters that Tehran wants a permanent ceasefire that includes guarantees it will not be attacked again by the United States and Israel. They said Iran had received messages from mediators including Pakistan, Türkiye and Egypt.

The final deal is expected to include Iran’s 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 has yet to commit despite massive civilian and military aid.

“Iran has not yet responded,” a source said, adding that temporary ceasefire proposals backed by Pakistan, China and the United States have not yielded any commitments so far.

Chinese officials did not immediately respond to requests for comment.

The latest diplomatic move comes amid escalating hostilities that have raised concerns about disruption to shipping in the Strait of Hormuz, a critical artery for global oil supplies.

US President Donald Trump has in recent days publicly pressed for a quick end to the conflict and warned of consequences if a ceasefire is not reached soon.

The conflict increased volatility in energy markets; Traders are closely monitoring any developments that could affect the flow through the strait.
