In a post on Truth Social, Trump declared: "The Deal with the Islamic Republic of Iran is now complete."

"Congratulations to all! I hereby fully authorize the toll-free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States naval blockade. Ships of the world, start your engines. Let the oil flow!" Trump wrote.

Describing it as a "great deal," Trump said the agreement would bring peace and security to the region.

"Many presidents have tried to make peace with Iran, and all have failed before me. The leaders of the region have, for the first time, found a President who can help them achieve real peace. With the opening of the Strait upon the signing of the deal on Friday, for purposes of mine removal, oil will flow on both ends again for the region, and the world," he said.

Iran's Deputy Foreign Minister Kazem Gharibabadi also confirmed the agreement. Quoting him, the Iranian Consulate in Hyderabad posted on X: "The immediate and permanent end of the war and all military operations on various fronts, including Lebanon, will be announced starting tonight."

However, Gharibabadi stressed that the understanding should not be viewed as a formal peace accord.

"This is not a peace deal. This is a memorandum of understanding (MoU) aimed at stopping U.S.-Israeli war crimes against other nations—crimes that will never be erased from the collective memory of Iranians," he said.

The Iranian official further added: "We defeated the U.S. on the military battlefield, and in this memorandum they pledged to end the war. Iran's armed forces will always have their hand on the trigger to confront the conspiracies of the enemies."

The exact details and terms of the agreement remain unclear.

Welcoming the breakthrough, UN Secretary-General António Guterres wrote on X: "I warmly congratulate the U.S. and Iran for having reached a peace deal that provides for an immediate and permanent ceasefire, the reopening of the Strait of Hormuz, as well as a framework for further negotiations. This represents a critical step towards the peaceful settlement of the conflict."

He further said: "My deep appreciation goes to Pakistan, Qatar, Egypt, Saudi Arabia, Türkiye, and other regional countries for the constructive role they played in supporting the negotiations that led to the peace deal."
