Speaking publicly, Gharibabadi said Switzerland would be involved in the signing process.

"The official signing of the memorandum will take place on Friday between the main parties, with Switzerland involved," he said.

The Iranian official also outlined what he described as the main elements of the agreement.

"The first point is the immediate and permanent end of the war and military operations, in fact, on various fronts, including in Lebanon," he claimed.

"You saw this in the position announced by the Prime Minister of Pakistan, where it was explicitly stated that a permanent and immediate end to the war has been declared on all fronts, including Lebanon."

His remarks came after Pakistani Prime Minister Shehbaz Sharif said there had been "the immediate and permanent termination of military operations on all fronts, including in Lebanon".

Gharibabadi also said the agreement addressed maritime restrictions imposed on Iran .

"The second event that occurred, which the US President also announced in his statement, is the lifting and termination of the naval blockade that the US had, in fact, imposed against the Islamic Republic of Iran," he stated.

While both Tehran and Washington have confirmed that an agreement has been reached, neither side has publicly released the full contents of the deal.

Media reports have suggested the agreement could include a 60-day ceasefire, the reopening of the Strait of Hormuz, the end of the US naval blockade, sanctions relief for Iran and renewed discussions on Iran's nuclear programme.

However, Israel has stated that it is not a party to the agreement.
