President Donald Trump announced in a Saturday evening social media post that Middle Eastern allies have reached the parameters of a deal to end the Iran war, prompting him to hold off on ordering new strikes in the five-month-old conflict.

Trump stated that the emerging agreement "would include the Immediate, Complete, and Total OPENING OF THE HORMUZ STRAIT, and an end to Iran's nuclear threat." The Strait of Hormuz is one of the world's most critical energy chokepoints, through which roughly a fifth of global oil consumption transits daily. Disruptions there have contributed to elevated oil prices and supply-chain anxieties throughout the conflict, intensifying pressure on Gulf states whose economies depend on stable energy exports.

"Based on this request, I have agreed, for the future benefit of the WORLD and, likewise, the survival of a successful and prosperous Iran, to cancel the attack, subject to being able to rapidly make a DEAL," Trump said. He added that Israel has agreed to join the United States in the commitment to pursue completion of the agreement with Iran, which would bring an end to the war.

The announcement followed a phone call earlier in the day between Trump and Saudi Crown Prince Mohammed bin Salman, the kingdom's de facto leader, who raised concerns about the potential for U.S. escalation, according to a person familiar with the discussion. The call was first reported by Axios.

According to the person briefed on the call's substance but not authorized to comment publicly, the Saudis are concerned that if the U.S. targets Iran's energy infrastructure or conducts large-scale strikes on other key infrastructure, Tehran could retaliate by attacking the kingdom's and other Gulf nations' energy infrastructure. Gulf energy facilities have faced such crossfire before, including a 2019 missile and drone assault on Saudi Aramco processing facilities that temporarily cut a significant share of the kingdom's oil output — an attack the U.S. and Saudis attributed to Iran, which Tehran denied.

A White House official, who was not authorized to comment publicly and requested anonymity, confirmed that the two leaders spoke on Saturday but declined to provide details about the substance of their conversation.

Earlier in the week, Saudi Arabia joined the United States in striking multiple logistics and weapons sites used by Iranian-backed militias in Iraq. At the same time, Riyadh has been urging both Washington and Tehran to return to the negotiating table to find a resolution to the conflict. The crown prince also dispatched his brother, Saudi Defense Minister Khalid bin Salman, to Washington for separate meetings with Trump and Vice President JD Vance to discuss Iran strategy.

The stakes surrounding continued U.S. military action remain high for Trump and his party. The conflict, which is unpopular among many Americans, has disrupted the global economy just months ahead of critical midterm elections in November.

The president had vowed retaliatory action after the U.S. military thwarted a surprise attack by Iran on a U.S. base in Jordan earlier in the week. On Friday, Trump told reporters that "we just want to win" in Iran and said the U.S. will hit Iran "very hard" until they can't take it anymore. White House Press Secretary Karoline Leavitt expressed frustration that Tehran had signed a memorandum of understanding with the U.S. last month on a truce but then quickly "broke it, shot at commercial ships, and killed American soldiers."

On Saturday, the U.S. State Department issued new security alerts for Americans in 10 countries across the region, urging heightened caution due to escalating tensions with Iran. The warnings — covering Bahrain, Israel, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, and the United Arab Emirates — advised U.S. citizens to prepare for possible flight cancellations, temporary airspace closures, and other travel disruptions.
