Tehran said Friday it had not reached a final decision on a deal to end the Middle East war, despite US President Donald Trump claiming an agreement could be signed in days and cancelling threatened strikes on Iran.Trump's statements fueled a stock market rally and tanked oil prices, again spurring hopes a resolution was nearing in the war triggered by US-Israeli strikes in February. Claiming that talks with Iran had been "brought to the highest level of Iranian leadership and approved," Trump said he had "cancelled the scheduled strikes and bombings against Iran this evening.""Time and place of the signing to be announced shortly," he added.Trump said the finer points of the arrangement had been approved by the United States and its allies in the region, including Israel, with which Washington jointly launched the war in February.However, Iran's foreign ministry spokesman Esmaeil Baqaei said Tehran "had not reached a final conclusion on the agreement".He added that "most of the text of the agreement was finalized, but the problem began when the US side made new demands and changed its positions."The Tasnim news agency noted that Trump had announced a deal was imminent 38 times in the previous two months. "Until Iran announces the matter of a potential understanding, any news from Trump on this subject should be regarded the same as his previous messaging," it noted. Later Trump doubled down, telling reporters "I understand the answer is yes," when asked if Iranian supreme leader Ayatollah Mojtaba Khamenei had approved the deal.Prime Minister Benjamin Netanyahu's office said the Israeli leader spoke to Trump, who vowed any memorandum of understanding would include the removal of Tehran's enriched nuclear material as well as dismantling of missile infrastructure.- 'Approved by all parties' -The war -- which began February 28 with a wave of US-Israeli strikes on Iran that killed supreme leader Ayatollah Ali Khamenei -- paused under an April truce. But efforts to hammer out a permanent end to the fighting appeared stalled.Tehran's mayor said Thursday the former supreme leader's funeral would be delayed to the end of June or start of July.
