US Vice President JD Vance said on Sunday there was no deal with Iran after 21 hours of negotiations in Pakistan, citing shortcomings in the talks and saying Iran had chosen not to accept US terms.
The talks in Islamabad were the first direct US-Iranian meeting in more than a decade and the highest-level discussions since the 1979 Islamic Revolution.
The outcome could determine the fate of the fragile two-week ceasefire and the reopening of the Strait of Hormuz, a chokepoint for about 20% of global energy supplies that Iran has blocked since the war began. The conflict has sent global oil prices soaring and killed thousands of people.
Vance, special envoy Steve Witkoff and President Donald Trump's son-in-law Jared Kushner met Iranian Parliamentary Speaker Mohammad Baqer Qalibaf and Foreign Minister Abbas Araqchi for two hours before a rest, according to a source from mediator Pakistan.
