Iran and the United States received a plan to end the fighting that could take effect Monday and reopen the Strait of Hormuz, a source familiar with the proposals told Reuters Monday.
Pakistan finalized a framework to end the hostilities and transmitted it to Iran and the US overnight, the source said. The framework takes a two-phase approach, beginning with an immediate ceasefire followed by a comprehensive agreement. "All elements must be agreed upon today," the source said, adding that the initial understanding would be formalized as a memorandum of understanding concluded electronically through Pakistan, the sole communication channel in the talks.

Iran's Foreign Ministry issued a brief statement declaring that "negotiations are incompatible with ultimatums." The statement accused the US and Israel of "committing crimes worse than those of Hitler."
Axios reported Sunday that the United States, Iran, and regional mediators were discussing a possible 45-day ceasefire as part of a two-phase deal that could lead to a permanent end to the war, citing American, Israeli, and regional sources.
The source told Reuters that Pakistan's army chief, Field Marshal Asim Munir, had been in contact "throughout the night" with US Vice President JD Vance, special envoy Steve Witkoff, and Iranian Foreign Minister Abbas Araghchi. Under the proposal, a ceasefire would take effect immediately, reopening the Strait of Hormuz, with 15 to 20 days allotted to finalize a broader agreement. The deal, provisionally named the "Islamabad Agreement," would include a regional framework for the strait, with final face-to-face talks held in Islamabad.
No immediate response was received from American or Iranian officials. Pakistan's Foreign Ministry spokesperson, Tahir Andrabi, declined to comment. Iranian officials had previously told Reuters that Tehran was seeking a permanent ceasefire with guarantees that it would not be attacked again by the US or Israel. They said Iran had received messages from mediators, including Pakistan, Turkey, and Egypt.
Iran's commitment to forgo nuclear weapons
The final agreement is expected to include Iranian commitments to renounce nuclear weapons in exchange for sanctions relief and the release of frozen assets, the source said. Two Pakistani sources said Iran had not yet made a commitment, despite heightened civilian and military activity.
"Iran has not yet responded," one source said, adding that proposals backed by Pakistan, China, and the United States for a temporary ceasefire had not produced a commitment thus far.
No immediate response was received from Chinese officials to requests for comment. The latest diplomatic push comes against a backdrop of escalating hostilities that have raised concerns about disruptions to shipping through the Strait of Hormuz, a critical artery for global oil supplies.
US President Donald Trump had in recent days publicly pressed for a swift end to the conflict, warning of consequences if a ceasefire was not reached within a short time. The conflict has heightened volatility in energy markets, with traders closely tracking every development that could affect oil flows through the strait.
