US–Iran deal talks: Pakistan signals 24-hour breakthrough as Tehran rejects Sunday signing claim

A long-awaited agreement between the United States and Iran could be finalised, US President Donald Trump said, adding that the deal was “scheduled to get signed tomorrow” and that the Strait of Hormuz would reopen immediately after the signing.

However, Iran’s foreign ministry spokesperson said no signing is expected on Sunday, while leaving open the possibility of a deal in the coming days.

Meanwhile, Pakistani Prime Minister Shehbaz Sharif said the agreement could be finalised within 24 hours, adding that both sides are closer than ever to ending months of conflict in the Middle East. 

Trump says deal to be signed Sunday, Hormuz to reopen

Trump said a long-awaited Middle East deal is scheduled to be signed on Sunday, adding that the Strait of Hormuz would open immediately afterward.

“The Deal is scheduled to get signed tomorrow, and immediately after it is signed, the Hormuz Strait is OPEN TO ALL,” he said on Truth Social.

Trump also said the US would later move to secure and destroy Iran’s stockpile of enriched uranium, adding it would be “downblended and destroyed” either in Iran or the United States.

He warned of “the ultimate alternative” if the plan is not implemented, while Iran has maintained its right to enrich uranium throughout negotiations.

Iran criticises Trump’s push for signing

Iran’s Islamic Revolutionary Guard Corps (IRGC), however, has denied reports that an agreement with the United States will be signed on Sunday, criticising Trump’s “unusual insistence” on that timeline.

The IRGC said Iranian negotiators have made clear that no final memorandum has been reached and that a Sunday signing “is definitely not happening.”

It also suggested the timing could be politically motivated, with some observers alleging Trump may be seeking to align the announcement with his birthday on June 14.

Pakistan signals possible 24-hour breakthrough

Pakistan, which has played a key mediating role, said Washington and Tehran have made significant progress in negotiations.

Shehbaz Sharif wrote on X that “finalisation is likely within the next 24 hours,” adding that preparations are underway for an electronic signing of the deal, followed by technical-level talks in the coming week.

Iranian Foreign Minister Abbas Araghchi also expressed cautious optimism, saying most issues have been agreed, though final approval is still pending.

Iran says timing of signing remains unclear

Despite the optimism, Iran’s foreign ministry has rejected reports that a deal will be signed on Sunday.

Spokesman Esmaeil Baqaei said, “It will not be tomorrow,” while stressing that the timing remains uncertain. He added that a signing in the coming days “cannot be ruled out,” indicating that talks are still ongoing but not finalised. 

Strait of Hormuz remains key flashpoint

A central issue in the negotiations is the Strait of Hormuz, a critical global route for oil and gas shipments.

The emerging framework reportedly includes provisions to reopen the waterway, ease restrictions, and redefine transit arrangements after months of disruption linked to the conflict.

However, divisions remain over control of the strait, sanctions relief, and Iran’s nuclear programme.

Nuclear terms and sanctions relief on table

Officials briefed on the talks say the draft agreement could include:

• Phased lifting of US sanctions on Iran

• Release of frozen Iranian assets

• Steps to address Iran’s enriched uranium stockpile

• A 60-day technical phase to finalise nuclear arrangements

Washington has pushed for the dismantling or relocation of enriched uranium, while Tehran insists its nuclear programme is peaceful.

Renewed clashes raise tensions

Despite diplomatic progress, tensions remain on the ground.

US Central Command said it intercepted multiple Iranian drones targeting commercial ships in the Strait of Hormuz, calling the attacks an attempt to disrupt maritime traffic. Iran has not formally responded to the latest claims.

Tensions continue despite talks

The diplomatic uncertainty comes amid continued volatility in the region, including reported drone interceptions in the Strait of Hormuz and ongoing disputes over maritime control.

Despite optimism from some mediators, both sides appear to be publicly cautious as negotiations reach a critical stage.

Conflicting messaging from both sides

US President Donald Trump rejected suggestions that the deal favours Iran, saying leaked versions do not reflect the actual agreement.

Iranian officials, meanwhile, have urged caution, stressing that no final deal exists until all terms are fully agreed and signed.

What happens next

If approved, officials say the agreement could still be signed remotely within days, followed by detailed technical negotiations.

Switzerland has offered to host a formal signing ceremony, but final arrangements remain unclear.

For now, mediators maintain that momentum is strong—while acknowledging that major political and technical hurdles still stand in the way of a final breakthrough.
