ISLAMABAD (AP) — Last-minute ceasefire talks between the United States and Iran looked uncertain Tuesday as a two-week truce was set to expire and both countries warned that, without a deal, they were prepared to resume fighting.

U.S. Vice President JD Vance, expected to lead U.S. negotiators if talks continue in Pakistan, remained in Washington on Tuesday, a White House official said. And Pakistan, which has been urging both sides to return to Islamabad, said it was still awaiting confirmation on whether Iran would participate.

Earlier in the day, two regional officials said Washington and Tehran had signaled they would hold a second round of talks, with Vance leading the U.S. team and Iranian parliament speaker Mohammad Bagher Qalibaf as its top negotiator. Both spoke on condition of anonymity because they were not authorized to brief reporters.

But Pakistan’s information minister, Attaullah Tarar, said later Tuesday on X that Iran had not formally confirmed its participation, which was set to expire Wednesday. And Iranian Foreign Ministry spokesman Esmail Baghaei told Iran’s state TV there has been “no final decision” on whether to attend ceasefire talks because of “unacceptable actions from the American counterpart.”

Vance had policy meetings scheduled at the White House on Wednesday morning, said a White House official who was not authorized to speak publicly and spoke on condition of anonymity. The vice president’s office and the White House did not immediately respond to messages asking whether Vance still intends to travel to Pakistan.

Trump says he doesn't favor extending ceasefire

Both sides remain dug in rhetorically. U.S. President Donald Trump has warned that “lots of bombs” will “start going off” if there’s no agreement before the ceasefire deadline, and Iran’s chief negotiator said that Tehran has “new cards on the battlefield” that haven't yet been revealed.

The ceasefire, which began April 8, could be extended if talks resume, though Trump said in an interview Tuesday with CNBC: “Well, I don't want to do that.”

"We don’t have that much time,” Trump said, adding that Iran “had a choice” and “they have to negotiate.”

White House officials have said that Vance would lead the American delegation, but Iran hasn't said who it might send. Iranian state television on Tuesday broadcast a message saying that “no delegation from Iran has visited Islamabad … so far.”
