President Donald Trump stated that an agreement to halt conflict between the US and Iran is planned for signing on Sunday, even as Iran raised questions about the schedule.

In a social media post, Trump indicated that the Strait of Hormuz, an important shipping lane, would become accessible to everyone once the pact is finalized.

Pakistan, acting as a primary mediator, announced on Saturday that the agreement was expected to be completed within 24 hours, with arrangements underway for an electronic signing ceremony.

Prior to Trump's statement, Iranian foreign ministry spokesman Esmail Baghaei advised caution on the timeline, noting that the exact date for signing the memorandum of understanding remained to be determined and would not occur on Sunday.

A delegation from Qatar, another mediator in the discussions, arrived in Tehran on Sunday according to Iranian reports.

The purpose of the visit and its potential effect on the signing schedule were not immediately clear.

Trump posted on Truth Social on Saturday that the deal would be signed the following day, after which the Hormuz Strait would open to all traffic.

Referring to Iran's enriched uranium reserves, he added that once conditions stabilized, the materials would be collected and later destroyed.

Western nations have long accused Iran of seeking nuclear weapons, claims Tehran rejects by insisting its program serves only peaceful goals such as power generation and research.

Trump warned that if progress stalled, the US held a powerful backup option that he hoped would never be required.

Pakistani Prime Minister Shehbaz Sharif said earlier on Saturday that the sides were nearer to a peace accord than at any prior point.

He added that finalization was anticipated within the next day, after which Pakistan would facilitate the electronic signing and begin technical discussions the following week.

On Friday, Iran's Foreign Minister Seyed Abbas Araghchi confirmed that an accord with the US was near, one that would conclude fighting between Israel and Hezbollah in Lebanon.

Nuclear negotiations would follow at a later stage.

US officials verified key elements, noting that economic relief for Iran would be linked to its fulfillment of commitments.

Similar versions of the agreement have been anticipated multiple times in recent months yet remained unfinished.

The conflict erupted after US and Israeli strikes on Iran on 28 February, which prompted Iranian attacks on Israel and Gulf allies along with the closure of the Strait of Hormuz, a vital route for oil and gas shipments.

Although a ceasefire was reached in April, occasional exchanges of fire have persisted.

Earlier US reports suggested the Israel-Hezbollah conflict might be excluded from this arrangement, despite Iran's reported insistence on its inclusion.

Israel, which is not a participant in the US-Iran deal, has stated it will continue operations against Hezbollah in response to attacks in northern Israel.

On Sunday, Israel directed residents of 29 villages in southern Lebanon to evacuate, an action that often precedes airstrikes.

Israeli army spokesman Col Avichay Adraee cited Hezbollah violations of the ceasefire as justification for the response to suspected drone incidents.
