The United States and Iran are close to agreeing on a memorandum of understanding aimed at ending the war, two regional officials and a diplomat said Saturday, as the United States has weighed a new round of attacks on the Islamic Republic.

Iran signaled “narrowing differences” in negotiations with the U.S. after Pakistan’s army chief held more talks in Tehran, and U.S. Secretary of State Marco Rubio told journalists in India that “there’s been some progress made” and “there may be news later today.”

The officials and diplomat expressed hope that a final decision on the Pakistan-prepared draft could come within 48 hours as both sides review it. They spoke on condition of anonymity because they were not authorized to brief the media.

They said Vice President JD Vance and envoys Steve Witkoff and Jared Kushner played significant roles in helping bridge remaining gaps, and that Qatar played a key role by sending a senior official to Tehran to support Pakistan’s mediation efforts.

Still, both Iran and the U.S. emphasized their key positions and have warned of the risks of resuming attacks and disrupting their ceasefire. Rubio repeated the U.S. stance that Iran can never have a nuclear weapon and must turn over its highly enriched uranium, and the Strait of Hormuz must be open.
