ISTANBUL/WASHINGTON - The United States and Iran said Sunday they had failed to reach a peace agreement after holding marathon face-to-face negotiations, with differences remaining over the reopening of the Strait of Hormuz and other major sticking points.

"We go back to the United States having not come to an agreement. We've made very clear what our red lines are, what things we're willing to accommodate them on and what things we're not willing to accommodate them on," U.S. Vice President JD Vance said after the talks in Pakistan. "They have chosen not to accept our terms."
