Washington and Tehran have agreed to an initial 60-day ceasefire and verification framework, U.S. Vice President JD Vance told CNBC on June 16, though technical details remain unresolved. A U.S. official said Trump, Vance and Iranian parliament speaker Mohammad Bagher Ghalibaf signed a memorandum of understanding as a preliminary step before a final deal. Swiss officials separately said a possible signing ceremony is provisionally scheduled for June 19, a Friday, at Bürgenstock in central Switzerland, indicating the event has not been finalized.
