A possible breakthrough in talks between the United States and Iran could be finalized on Sunday, with expectations that a formal agreement will be signed to ease tensions in the Middle East.

Donald Trump said the deal is scheduled for signing on Sunday, adding that the Strait of Hormuz would be reopened immediately afterward, restoring access to one of the world’s most important oil shipping routes.

The proposed agreement comes after weeks of strained relations and disruptions in the Gulf, where maritime traffic has been affected by ongoing hostilities and security concerns. The Strait of Hormuz, in particular, has remained a major flashpoint due to its strategic importance in global energy supply.

Diplomatic efforts involving regional mediators, including Pakistan, suggest negotiations are in their final stages. Pakistani Prime Minister Shehbaz Sharif said the agreement could be concluded within 24 hours, with the signing expected to take place electronically.

Iranian officials, however, have offered a more cautious position, saying the timing is not fully confirmed despite signs of progress in discussions.

Key issues in the talks include control of the Strait of Hormuz and Iran’s nuclear programme. Tehran insists it must retain authority over the waterway, while Washington has opposed any arrangement that leaves full control in Iranian hands.

Iran’s Foreign Minister Abbas Araghchi has maintained that any handling of enriched uranium must remain within Iran, while the United States continues to push for stricter limits.

Despite diplomatic momentum, uncertainty remains over final terms, with both sides still navigating sensitive political and security demands.
