Pakistan handed over the American proposal to Iran, a senior Iranian source told Reuters

Pakistan has delivered a US proposal to Iran, a senior Iranian source told Reuters on Wednesday, but the venue for any talks between Tehran and Washington to end the war has not yet been decided.

The source, who asked not to be named because of the sensitivity of the matter, did not reveal details of the proposal or whether it was the reported 15-point US framework to end the war.

The source added that Turkey was helping to explore ways to end the war and said that “either Turkey or Pakistan is under consideration as the venue for such talks”.

The ongoing conflict between the United States and Iran escalated sharply following the February 28 “preemptive” strike against Iran by the United States and Israel following a series of direct military exchanges that marked one of the most dangerous confrontations between the two in years.

Tensions heightened after high-level Iranian leadership was hit by strikes, including reports of the death of Supreme Leader Ayatollah Ali Khamenei, a development that markedly increased the risk of a wider regional war.

The fighting has since involved missile and drone strikes, with Iranian attacks targeting US positions and assets, resulting in casualties and fueling fears of further escalation. Washington has strengthened its military posture while seeking support from allies as Tehran has anticipated defiance and conditional openness to talks. In recent days, diplomatic efforts have accelerated, with backchannel contacts and proposals – including a reported US framework to end hostilities – being passed through intermediaries such as Pakistan and Turkey.

Although no ceasefire has been reached, attention is increasingly shifting to potential negotiations, amid concerns that a protracted conflict could destabilize energy markets, disrupt key shipping routes and further inflame an already volatile Middle East.
