However, Trump says an Iran agreement could be signed as soon as this weekend.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan in April failed to reach a peace deal.
Trump later announced the open-ended extension of the ceasefire and the continuation of a U.S. blockade until negotiations are concluded "one way or the other."
Iran's Foreign Minister Abbas Araghchi said that the Islamabad Memorandum of Understanding "has never been closer."
Araghchi asked the media to refrain from "speculation" about the content of the deal, saying "all details will be shared with the public in due course."
The Trump administration is moving forward with initial plans to hold a signing ceremony in Geneva as soon as this weekend, but despite President Donald Trump’s comments on Thursday, there’s still no indication that the Iran's supreme leader has approved the terms of the deal, according to several sources familiar with the matter.
The draft deal has been approved at high levels of the Iranian regime -- but this same rank of Iranian leaders previously accepted the terms of a draft memorandum of understanding late last month when negotiators from both sides believed they were close to an agreement, a U.S. official and another source tell ABC News.
At that time, Trump added additional nuclear provisions to the agreement that appeared to stall progress with the Iranians. The draft deal currently on the table still includes versions of these demands, including a commitment to address Iran’s stockpile of highly enriched uranium, but the language on that term has been softened somewhat, the sources said.

President Donald Trump pushed back against Iran on Friday, calling Iran’s alleged attack of an Indian ship leaving the Strait of Hormuz "unacceptable."
"They better get their act together, and FAST," Trump warned in a post on social media.
Trump also pushed back against claims Iran had made regarding a potential peace deal.
"The terms that Iran leaked out to the Fake News have NOTHING to do with the terms that were agreed to, in writing. What they said, including their weak and pathetic statement on having a deal, bears no relation to the truth. Very dishonorable people to deal with," Trump said.
U.S. forces shot down two Iranian one-way attack drones, according to a U.S. official.
"It appears Iran has attempted to strike commercial ships transiting the Strait of Hormuz tonight," the official said.
"Traffic flow through the Strait continues," the official said.
