Ahead of attending the long-awaited G7 summit in Évian, US President Donald Trump has announced a peace deal with Iran could be finalised on Sunday, paving the way for the opening of the Strait of Hormuz.

"The Deal is scheduled to get signed tomorrow, and immediately after it is signed, the Hormuz Strait is OPEN TO ALL," Trump said in a post on his Truth Social platform on Saturday.

Donald Trump also says the US will take Iran's enriched uranium 'dust' when 'all is calm'.

Trump's statement, however, ran counter to Iran's foreign ministry which indicated earlier in the day that the deal would not be signed on Sunday, according to state media reports.

Earlier, Pakistan's prime minister said on Saturday that a peace deal between the United States and Iran is likely to be finalised within the next 24 hours.
