*As Iran’s Head of Parliament lashes back at Trump
Iran and the United States have received a plan to end hostilities that could come into effect on Monday and reopen the Strait of Hormuz, a source aware of the proposals said on Monday.
A framework to end hostilities has been put together by Pakistan and exchanged with Iran and the US overnight, the source said, outlining a two-tier approach with an immediate ceasefire followed by a comprehensive agreement.
“All elements need to be agreed today,” the source said, adding the initial understanding would be structured as a memorandum of understanding finalized electronically through Pakistan, the sole communication channel in the talks.
Axios first reported on 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 US, Israeli and regional sources.
The source told Reuters Pakistan’s army chief, Field Marshal 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.
Under the proposal, a ceasefire would take effect immediately, reopening the Strait of Hormuz, with 15–20 days to finalize 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.
On Monday, a senior Iranian official told Reuters that Iran won’t reopen the Strait of Hormuz in exchange for a “temporary ceasefire”, adding that Tehran views Washington as lacking the readiness for a permanent ceasefire.
The official confirmed Iran had received Pakistan’s proposal for an immediate ceasefire and was reviewing it, adding that Tehran does not accept being pressured to accept deadlines and make a decision.
There was no immediate response from US officials. Pakistan’s foreign office spokesperson Tahir Andrabi declined comment.
Iranian officials have previously told Reuters that Tehran was seeking a permanent ceasefire with guarantees they will not be attacked again by the US and Israel. They have said Iran has received messages from mediators including Pakistan, Turkiye and Egypt.
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 has yet to commit despite intensified civilian and military outreach.
The latest diplomatic push comes amid escalating hostilities that have raised concerns over disruption to shipping through the Strait of Hormuz, a critical artery for global oil supplies.
US President Donald Trump has in recent days publicly pressed for a rapid end to the conflict, warning of consequences if a ceasefire is not reached within a short timeframe.
Meanwhile, Iran’s parliamentary Speaker Mohammad Bagher Qalibaf dismissed Trump’s recent threats of targeting Iran’s infrastructure as “reckless” in a social media post on Sunday.
“You won’t gain anything through war crimes,” Qalibaf wrote on X. “The only real solution is respecting the rights of the Iranian people and ending this dangerous game.”
Tehran’s mission to the UN called the open threats to target civilian infrastructure “a direct and public incitement to terrorize civilians and clear evidence of intent to commit war crime.”
“The international community and all States have legal obligations to prevent such atrocious acts of war crimes,” the mission said in a post on the social platform X. “They must act now. Tomorrow is too late.”
Iran’s Deputy Foreign Minister Kazem Gharibabadi also said that Trump’s threats to strike power plants and bridges in Iran could amount to war crimes.
“The American president, as the highest official of his country, has publicly threatened to commit war crimes,” Gharibabadi said in a post on X, citing provisions of international law that could be breached.
“The threat to attack power plants and bridges (civilian infrastructure) is a war crime under Article 8(2)(b) of the Rome Statute of the International Criminal Court,” he added.
Iran’s ally Russia also condemned Trump’s threat
Moscow said Washington should abandon “the language of ultimatums” and return to negotiations, according to a Russian readout of Foreign Minister Sergei Lavrov’s latest call with his Iranian counterpart.
A former foreign minister and adviser to the supreme leader warned Sunday that “the resistance front” could target the Bab El-Mandeb Strait off the Red Sea, through which about 12 percent of the world’s trade typically passes.
“If the White House thinks of repeating its stupid mistakes, it will quickly realize that the flow of global energy and trade can be disrupted with a single signal,” Ali Akbar Velayati said on social media, signaling possible closure of the vital waterway if the US escalates attacks.
Iran leads the so-called “Axis of Resistance,” which includes armed groups in Lebanon, Iraq and Yemen, where Houthi rebels had in the past cut off transit through Bab El-Mandeb with attacks on vessels.
Iran has effectively stopped cargo traffic through the Strait of Hormuz during the conflict, leading to higher oil and gas prices globally.
*Iran floats a new condition for Strait of Hormuz reopening
Seyyed Mohammad Mehdi Tabatabaei, a presidential spokesperson, wrote Sunday on the social platform X that the reopening of the vital waterway can only happen if transit revenues are partially earmarked to compensate Iran for war damages.
There has been growing alarm over Iran’s grip on the Strait of Hormuz, critical for shipments of oil and gas from the Persian Gulf to Europe and Asia. Trump has threatened to attack Iran’s infrastructure if it fails to reopen the strait by Monday.
