US President Donald Trump signs a memorandum of understanding (MoU) with Iran at the Palace of Versailles on 18 June, according to multiple outlets citing videos and White House confirmation. Reporting says the signing takes place shortly before, or in connection with, a dinner hosted by French President Emmanuel Macron at Versailles, with Macron seated nearby during the event as shown in footage released by the French presidency.

Several sources frame the MoU as an initial step toward easing Middle East hostilities that have continued since February. They describe the agreement as aiming to end fighting on multiple fronts and to support a broader de-escalation process. Other reporting adds that key elements discussed publicly include a military ceasefire, an Iran pledge related to nuclear non-development, sanctions relief, and the release of frozen assets, though details of the full implementation process are characterized as pending.

Some outlets also report that Iranian President Masoud Pezeshkian signs the MoU as well, and that officials and observers discuss an upcoming official ceremony. Coverage also notes assertions that the agreement would contribute to reopening the Strait of Hormuz, while broader outcomes depend on further steps.
