Donald Trump has said he will decide imminently whether to extend the ceasefire between the US and Iran - but Tehran has already cast doubt over the deal. The blockade of the Strait of Hormuz 'will now be lifted' as part of a deal with the regime, the US President has confirmed as he is expected to make a 'final decision' on peace. 'I will be meeting now, in the Situation Room, to make a final determination,' he announced on Truth Social Friday, referring to the White House's nerve centre for monitoring global crises. Sources had said a deal was in the offing to extend the truce, which has been in place since early April, for another 60 days. The deal would also allow oil and gas shipments to resume through the Strait of Hormuz while negotiators tackle tricky issues such as Iran's nuclear programme.It would need to include opening the Strait of Hormuz and dismantling Tehran's capacity to make a nuclear weapon for the President to approve an agreement with the regime. 'Iran must agree that they will never have a Nuclear Weapon or Bomb. The Hormuz Strait must be immediately open, no tolls, for unrestricted shipping traffic, in both directions,' Mr Trump said, adding that Iran's nuclear material would be 'unearthed' by the US. However Iran's top negotiator, Mohammad Baqer Qalibaf, had earlier sounded sceptical of a deal being agreed.

No action will be taken before the other side acts. The winner of any agreement is the one who is better prepared for war the day after.' However Iran's semi-official Fars news agency cited informed sources on Friday as saying Mr Trump's latest comments about a potential deal to end the war were a 'mixture of truth and lies' which were an 'attempt to portray a fabricated victory.'The agency said the US President claimed that 'Iran was obligated to open the Strait of Hormuz without tolls, even though no such clause appears in the text of the agreement'.On the US President's assertion that Washington and Tehran would coordinate on destroying Iran's enriched uranium, Fars reported: 'Well-informed sources emphasised that not only does this not appear in the memorandum of understanding, but this claim is fundamentally baseless.'There was no provision to destroy nuclear materials in the sides' memorandum of understanding, the agency said. However there was agreement to release $12billion from Iran's frozen assets. The US-Iran war has so far killed thousands of people, mainly in Iran and Lebanon, and caused global economic pain by pushing up energy prices due to Iran's effective closure of the Strait of Hormuz.Oil prices fell and stocks rose on Friday over the potential deal.On Friday, Mr Trump said mines would be removed from the strait and ships trapped there may start to go home. In a post on Truth Social he said: 'Say HELLO to your wives, husbands, parents, and families from me, your favorite President!' Pakistan's foreign minister, Ishaq Dar, arrived in Washington on Friday for talks with US Secretary of State Marco Rubio (pictured together)He added that no money would be exchanged 'until further notice' - a possible reference to Iran's demands for toll payments in the strait, war damage reparations or a release of Iranian funds frozen abroad.Kazakhstan has signalled that it is willing to take Tehran's stockpile of uranium, enriched close to weapons-grade levels, if the US reaches a deal with Iran, the head of the UN nuclear watchdog, Rafael Grossi, told the Financial Times.Kazakhstan hosts an internationally controlled bank of low-enriched uranium to ensure fuel supplies for power stations in International Atomic Energy Agency member states.In further diplomatic movement, Pakistan's foreign minister, Ishaq Dar, arrived in Washington on Friday for talks with US Secretary of State Marco Rubio.Iran also wants sanctions lifted, US forces withdrawn from the region, and for any peace deal also to end Israel's offensive in Lebanon.Israel has displaced hundreds of thousands of people with a push deep into Lebanon in pursuit of Iran's main ally, the Hezbollah group. Israeli strikes have pummelled Lebanon's south and east as well as its capital, Beirut, killing more than 3,200 people, according to Lebanon's health ministry.Israel has said 23 of its soldiers and four civilians have been killed over the same period.
