London [UK], April 6 (ANI): The United States and Iran have received a plan to end hostilities, which could come in effect on Monday and result in the opening of the Strait of Hormuz, sources familiar with the proposals told Reuters.

As per the report by Reuters, the framework has been put together by Pakistan and exchanged with Iran and US overnight, the source said, noting of a two-tier 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 structured as a memorandum of understanding finalised electronically through Pakistan, which as per the Reuters report is the sole communication channel in the talks.

According to the report, the proposal would see a ceasefire to take effect immediately, reopening the Strait of Hormuz, with 15-20 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 Islamabad, Reuters noted.

While there was no immediate response from the American and Iranian officials, Pakistan's foreign office spokesperson Tahir Andrabi declined comment.

Reuters reported that Iranian officials had previously told Reuters that Tehran was seeking a permanent ceasefire with guarantees they will not be attacked again by the US and Israel and that Iran received messages from mediators including Pakistan, Turkey and Egypt.

According to the source cited by Reuters, Pakistan's army chief, Asim Munir, has been in contact 'all night long' with US Vice President JD Vance, special envoy Steve Witkoff and Iranian Foreign Minister Abbas Araqchi.

The report further noted 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 is yet to commit despite intensified civilian and military outreach. 'Iran has not responded yet,' one source said, and mentioned that 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.

The recent development comes amid the backdrop of the deadline set by US President Donald Trump fast approaching for Iran, Axios reported on Sunday (local time), citing sources that the US, Iran and a group of regional mediators are discussing the terms for a potential 45-day ceasefire that could result in a permanent end to the war.
