Signal US and Iran Reach Tentative 60-Day Ceasefire Memorandum of Understanding

Summary

The United States and Iran reached a preliminary 60-day ceasefire memorandum of understanding on 29 May 2026, though it was still awaiting President Trump's final approval. Pakistan, through Deputy Prime Minister and Foreign Minister Ishaq Dar, mediated the negotiations, with a meeting scheduled between Dar and US Secretary of State Marco Rubio. Under the terms, shipping through the Strait of Hormuz would become "unrestricted" with no tolls or harassment, Iran would remove all mines within 30 days, and the US naval blockade on Iranian ports would lift proportionally. Iran committed to not pursuing nuclear weapons, with uranium enrichment to be discussed during the 60-day negotiation window, while the US agreed to discuss sanctions relief, unfreeze Iranian assets and include a humanitarian aid mechanism; the agreement also provided for Israel's war on Lebanon to end. In the days before the deal, fighting continued: US forces struck near the Strait of Hormuz, CENTCOM shot down five Iranian drones and struck Bandar Abbas on 26 May, both sides carried out attacks on 27 May despite the truce, and Kuwait intercepted hostile missiles and drones on the morning of 29 May.
