World leaders, including those from the G7, along with senior US lawmakers, welcomed a memorandum signed between the United States and Iran, with supporters describing it as a breakthrough that could reopen the Strait of Hormuz, ease regional tensions and advance negotiations over Tehran's nuclear programme.

The White House said President Donald Trump and Vice President JD Vance had secured a Memorandum of Understanding with Iran that would ensure Tehran "will never obtain a nuclear weapon", reopen the Strait of Hormuz to free navigation and create a framework for future diplomacy.
