A deal to end fighting between the US and Iran is "scheduled to get signed" on Sunday, US President Donald Trump has said – but Iran has cast doubt on the timing.
In a post on social media, Trump also said the Strait of Hormuz, a key shipping route, would be "open to all" following the deal.
Pakistan, a key mediator, also said finalisation of the deal was expected within 24 hours and they were "preparing for the electronic signing".
Before Trump's comments Iranian Foreign Ministry spokesman Esmaeil Baghaei expressed caution saying: "We will have to wait and see about the exact date of the signing of the memorandum of understanding, although it will not be tomorrow."
In Saturday's post on Truth Social, Trump wrote: "The Deal is scheduled to get signed tomorrow, and immediately after it is signed, the Hormuz Strait is OPEN TO ALL."
The US president also stressed that the deal would be "A WALL TO NO NUCLEAR WEAPON!"
In an apparent reference to Iran's enriched uranium stockpiles, Trump added that "at the appropriate time, when all is calm, we will go in and get the Nuclear Dust", adding it would later be destroyed.
For decades, Iran has been accused by Western countries of trying to build a nuclear weapon. It has denied the accusations saying its programme is for peaceful purposes – to generate electricity and for research purposes.
Trump also warned that if things would not "work out quickly, easily and smoothly", Washington had "the ultimate alternative, hopefully never to be used again!"
Earlier on Saturday, Pakistani Prime Minister Shehbaz Sharif said that "we are closer to a peace deal than ever before".
"With finalisation likely expected in the next 24 hours, Pakistan is preparing for the electronic signing of the peace deal immediately after, followed by technical level talks next week," Sharif wrote on X.
On Friday, Iran's Foreign Minister Seyed Abbas Araghchi also said that a deal with the US was close.
The agreement envisaged an end to the conflict between Israel and Hezbollah in Lebanon, he said.
Araghchi told Iran's state TV that the deal included reopening the Strait of Hormuz and also the lifting of a US blockade of Iranian ports.
However, he said talks on Iran's nuclear programme would begin later.
US officials have confirmed some of the details of the agreement, saying economic benefits for Iran would depend on Tehran meeting its obligations.
Previous reports from the US had suggested Lebanon may not be part of this deal – with Iran reportedly insisting on it.
The war began with US and Israeli strikes across Iran on 28 February, prompting Iran to attack Israel and US-allied states in the Gulf – as well as effectively closing the Strait of Hormuz, a key shipping route for the world's oil and liquefied natural gas.
Crews erected scaffolding on Friday as onlookers gathered into the evening, though storms delayed the work until Saturday.
The World Cup officially kicked off this week – but alongside the football, there are questions around heat, cost, the environmental impact and travel restrictions.
Niño Guerrero was killed in a "swift and lethal kinetic strike," the US President wrote in a social media post.
The approval marks a key development in the merger that will reshape media, allowing the continue of the takeover of the Hollywood studio, which owns CNN and HBO.
Earlier, Canada hosted its own opening ceremony in Toronto, featuring singers Alanis Morrisette and Michael Bublé.
