TEHRAN -- A source close to Iran's negotiating team has denied reports claiming that the text of a proposed memorandum of understanding (MoU) between Iran and the United States had been finalized, Iran's semi-official Tasnim news agency reported Thursday.

The source told Tasnim that reports suggesting the text was merely awaiting formal announcement by the two sides were "not consistent with the facts," adding that the document "has not yet been finalized."

According to the source, Iran has not formally informed Pakistani mediators that the text has been completed.

The source stressed that if the agreement text is ultimately finalized, Iran will officially notify the Pakistani mediators and make the matter public. Until then, any Western reports claiming the agreement has already been completed "lack credibility," the source added.

Earlier in the day, US media Axios reported that US and Iranian negotiators had reached an agreement on an MoU to extend the ceasefire by 60 days and launch talks on Iran's nuclear program.
