US President Donald Trump said Saturday he would order American forces to suspend further strikes on Iran, claiming that key Middle East allies had agreed on the basic framework of a deal aimed at ending the five-month-long war.

In a social media post, Trump said the proposed agreement would ensure the “immediate, complete and total” reopening of the Strait of Hormuz and eliminate what he described as Iran’s nuclear threat.

He said he had decided to cancel a planned attack “for the future benefit of the world” and for “a successful and prosperous Iran,” while making clear the decision depends on the parties being able to quickly reach a final agreement. Trump also said Israel had agreed to work with the United States to complete the deal. Iran did not immediately respond publicly.

The announcement came a day after Trump suggested the US was close to launching renewed large-scale strikes to pressure Tehran into negotiations.

The US and Israel launched attacks on Iran on Feb. 28, saying the campaign was intended to weaken Tehran’s missile capabilities, stop it from developing nuclear weapons and end its support for allied armed groups. However, the goals and timeline of the conflict have shifted repeatedly, and an earlier ceasefire agreement reached in mid-June collapsed within weeks.

Meanwhile, Saudi Crown Prince Mohammed bin Salman expressed concern during a phone call with Trump that any escalation could trigger Iranian attacks on Saudi and other Gulf states’ energy infrastructure, according to a person familiar with the discussion.

Separately, the US State Department issued fresh security alerts for Americans across several Middle Eastern countries, warning of possible flight cancellations, temporary airspace closures and other travel disruptions. Iran has also repeatedly targeted vessels passing through the Strait of Hormuz without its authorization during the conflict.
