The framework for ending the Iranian conflict has been drafted and discussed by Pakistan with Iran and the US last night (April 5), the source added.
This document outlines a two-stage approach with an immediate ceasefire, followed by a comprehensive agreement.
All factors need to be agreed upon today," the source added. The exchanges will be structured in the form of an electronically completed memorandum through Pakistan - the only communication channel in the negotiations.
Sources revealed that Pakistani Army Commander, Marshal Asim Munir, had contact "all night" with US Vice President JD Vance, US Special Envoy for the Middle East Steve Witkoff and Iranian Foreign Minister Abbas Araghchi.
According to the proposal, the ceasefire will take effect immediately, the Strait of Hormuz will reopen and there will be 15-20 days to complete a more comprehensive agreement.
This agreement, tentatively called the "Islamabad Agreement", will include a regional framework for the Strait of Hormuz, with final direct negotiations held in Islamabad.
The final agreement is expected to include Iran's commitment not to pursue nuclear weapons, in exchange for sanctions being lifted and frozen assets being lifted.
Two sources from Pakistan said that Iran has not yet made any commitments despite strong civilian and military access efforts.
Previously, Axios reported that the US, Iran and mediators in the region are discussing a potential 45-day ceasefire within the framework of a two-stage agreement that could lead to an end to the conflict.
