Iran denies Trump's claim that new talks will begin on Monday

US President Donald Trump has said new talks with Iran will begin on Monday, after calling off what he said would have been "massive" strikes on the country.

In an earlier post on Truth Social, Trump said he had been asked by Iran and US allies in the Middle East to "hold off" on any attack as the "perimeters" of a deal had been agreed.

Iran's foreign ministry said there are no plans to receive a US delegation or send Iranians to Washington. Earlier talks have been facilitated through mediators.

The US president has repeatedly vowed that a negotiated end to the war is near, only for tit-for-tat strikes to resume.

In his remarks on Air Force One, Trump declined to outline a deadline for a deal to be struck with Tehran, adding: "We'll just see how it is. We're ready to go anytime we want... I'm not looking to kill people."

Trump added that Saudi Arabia's Crown Prince Mohammed Bin Salman - as well as US partners such as the United Arab Emirates and Qatar - had urged him against conducting strikes over the weekend.

"We were all set to go," Trump said. "The reason they asked is [that] they think there's a deal," he said. "There's a deal on Hormuz, and there will be a deal on the nuclear."

Iran's semi-official Mehr news agency denied that Tehran had asked the US to hold off on further military action, saying Trump's claims were "nothing but a new lie".

On Sunday, Iranian Foreign Minister Abbas Araghchi said that negotiations with Oman on a deal on the Strait of Hormuz were "on track for finalisation", according to Iranian media.

The US president has not yet made clear the venue for the talks on Monday, nor the potential attendees.

During his remarks on Air Force One, Trump said that the planned strikes would have been "the biggest attack since World War II", and could have derailed prospects of a negotiated end to the months-long war.
