U.S.-Iran talks end with no deal, Vance says

The U.S. and Iran didn't reach an agreement during marathon negotiations on Saturday in Pakistan, Vice President Vance said in a press conference in Islamabad.

The deadlock in the talks puts the two-week ceasefire agreed last week in limbo, with the possibility of renewed and escalating warfare.

Vance said the U.S. and Iran had "substantive discussions" over 21 hours but couldn't bridge the gaps.

"This is bad news for Iran much more than this is bad new for the U.S.," he stressed. "We have made very clear what our red lines are…and they have chosen not to accept our terms."

Vance said the U.S. wanted to a long-term "affirmative commitment" from Iran not to seek a nuclear weapon or the tools that would enable them to produce one quickly. "We haven't seen that yet, we hope that we will," he said.

Vance claimed the U.S. was "quite flexible and accommodating" and negotiated "in good faith" but couldn't make significant progress.

The U.S. and Iranian delegations met over several rounds in multiple formats. The talks began on Saturday and ended in the early hours of Sunday local time.

Vance said the U.S. negotiating team spoke with President Trump at least than half-a-dozen times during the day.

They also spoke with Secretary of State Marco Rubio, Defense Secretary Pete Hegseth, Treasury Secretary Scott Bessent and CENTCOM commander Amd. Brad Cooper.

"We leave here with a very simple proposal. A method of understanding that is our final and best offer. We will see if the Iranians accept it," Vance said.
