Iran's foreign ministry spokesperson denied on Monday holding any talks with the US during the past 24 days, shortly after President Donald Trump said the two sides had found "major points of agreement" in the past few days.
In recent days, friendly countries sent messages indicating that the US had requested talks to end the war, but Iran had not responded, State news agency IRNA quoted the ministry spokesperson as saying.
US President Donald Trump said on Monday he had given instructions to postpone any military strikes against Iranian power plants for five days, just hours ahead of a deadline that threatened further escalation in the conflict now in its fourth week.
Trump said in a post on Truth Social that the US and Iran have had "very good and productive" conversations with Iran over the past two days about a "complete and total resolution of hostilities in the Middle East'.
In his message, written entirely in capital letters, he said he had instructed the defense department to postpone the strikes pending the outcome of current talks.
On Saturday, Trump had warned that Iranian power plants would be destroyed if Tehran failed to "fully open" the Strait of Hormuz to all shipping within 48 hours. Trump set a deadline of around 7:44 p.m. EDT (2344 GMT) on Monday.
His comments sparked threats of retaliation from Iran's Revolutionary Guards, which said in a statement on Monday they would attack Israel's power plants and those supplying U.S. bases across the Gulf region if Trump followed through with his threat to "obliterate" Iran's power network.
More than 2,000 people have been killed in the war the US and Israel launched on February 28, which has upended markets, driven up fuel costs, fuelled global inflation fears and convulsed the postwar Western alliance.
The threat of strikes on Gulf electricity grids raised fears of mass disruption to desalination for drinking water, and further rattled oil markets.
