'Hormuz control is must': Iran withdraws from MoU, accuses US of violating ceasefire
WASHINGTON, DC: Iran has withdrawn from its Memorandum of Understanding (MoU) with the United States, accusing Washington of violating the agreement by reinstating a naval blockade on Iranian ports and ships.

He said the US had "completely dismantled" the June 17 MoU by imposing a naval blockade and vowed that Iran "will never request negotiations with the United States."
The Strait of Hormuz is one of the world's most critical shipping lanes, carrying about 20% of global oil trade. Iran had previously shut the waterway after joint US-Israeli strikes triggered the conflict earlier this year.

The announcement comes after President Donald Trump declared the ceasefire with Iran "over" and threatened a broader military campaign unless Tehran returned to negotiations.
"We're going to hit them very hard," Trump said, warning that future strikes could target Iran's power plants, bridges and energy infrastructure if no deal is reached.

The June MoU had aimed to end hostilities within 60 days, restore commercial shipping through the Strait of Hormuz and create a framework for resolving disputes over Iran's nuclear program.
Iran's withdrawal effectively ends that agreement, increasing the risk of further military escalation and renewed disruption to global energy markets as tensions between Tehran and Washington continue to intensify.
