U.S. Vice President JD Vance’s expected trip to Islamabad to lead peace talks with Iran has been called off for the day, CNN reported citing a White House official.

JD Vance was expected to lead a delegation of U.S. negotiators to Islamabad.

“In light of President Trump’s Truth Social post confirming the United States is awaiting a unified proposal from the Iranians, the trip to Pakistan will not be happening today. Any further updates on in-person meetings will be announced by the White House,” the official said in a statement, according to CNN.

President Donald Trump announced in a Truth Social post earlier today that he’d extend an existing ceasefire with Iran as the administration waits for a “unified proposal” from what he described as the “seriously fractured” government.

Iran earlier said it does not want to negotiate under threats.

The negotiations held between the United States and Iran in Islamabad on April 11–12 ended without any deal.
