International mediators from Egypt, Pakistan, and Turkey have formally submitted a draft proposal to Iran and the United States calling for a 45-day ceasefire and the immediate reopening of the Strait of Hormuz.

According to Middle Eastern officials speaking to the Associated Press on the condition of anonymity, the initiative was delivered late Sunday to Iranian Foreign Minister Abbas Araghchi and US envoy Steve Witkoff.

The proposal aims to establish a temporary cessation of hostilities to facilitate high-level negotiations toward a permanent peace agreement; however, neither Tehran nor Washington has issued an official response to the terms.

The diplomatic overture comes amidst a sharp escalation in regional violence.

Iranian state media recently confirmed the death of Maj. Gen. Majid Khademi, the intelligence chief of the Revolutionary Guard, in an attack allegedly coordinated by US and Israeli forces.

Since Sunday, intensified airstrikes across Iran have claimed over 25 lives, while Iranian missile strikes on the Israeli city of Haifa have resulted in at least two confirmed fatalities and several missing persons.

The humanitarian toll continues to mount as the conflict, which began on February 28 following joint US-Israel strikes, enters its second month with thousands of casualties and widespread infrastructure damage reported on both sides.

US President Donald Trump has further heightened tensions by issuing a final warning to Tehran regarding the blockade of the Strait of Hormuz.

The President threatened to authorize major strikes against Iran’s domestic infrastructure—specifically targeting power plants and bridges—if the vital shipping lane is not reopened by a strict deadline.

This blockade has already significantly disrupted global oil shipments and sent fuel prices soaring, sparking international concern over the stability of the global economy and potential violations of international law regarding attacks on civilian-populated areas.

Despite the new 45-day roadmap offered by mediators, the lack of a formal commitment from either belligerent maintains a shroud of uncertainty over the region's immediate future.
