US-Iran Peace Talks in Islamabad Fail as Iran Rejects Negotiations

Efforts to revive diplomacy between the United States and Iran have stalled after Tehran declined to send negotiators to Pakistan for a new round of talks, according to Iranian officials. The announcement came less than 48 hours before a fragile ceasefire between the two nations was set to expire, raising concerns about a potential escalation in hostilities.

Iranian Ministry of Foreign Affairs spokesman Esmaeil Baghaei stated that Iran has “no plans to send negotiators to Islamabad” for discussions with the United States, accusing Washington of violating the ceasefire from its inception. He cited the ongoing U.S. Naval blockade of the Strait of Hormuz since April 13 and the recent capture of an Iranian container ship by American forces as clear breaches of the truce and international law.

Baghaei warned that if the U.S. And Israel launch further aggression, Iranian forces “will respond accordingly,” although reiterating that Tehran’s 10-point proposal—submitted prior to the first round of Islamabad talks—remains the foundation for any future negotiations. He added that Iran had formally informed Pakistan, the principal mediator, of these violations.

The breakdown follows a day of high-stakes face-to-face talks in Islamabad on April 11, 2026, which ended without agreement. U.S. Vice President J.D. Vance, leading the American delegation, confirmed the outcome in a press conference, stating, “The bad news is that we have not reached an agreement. And I think that’s bad news for Iran much more than it’s bad news for the US… they have chosen not to accept our terms.”

Vance emphasized that the core U.S. Demand remains an affirmative commitment from Iran that it will not seek a nuclear weapon or the means to rapidly develop one. Whereas he noted that Iran’s enrichment facilities have been damaged, he said the U.S. Did not observe the necessary long-term commitment to abandon nuclear ambitions.

The talks, which lasted 21 hours, marked the first direct engagement between U.S. And Iranian officials since 2015. They were held under a ceasefire intended to de-escalate a six-week conflict that has strained regional stability, particularly due to Israel’s continued strikes on Lebanon and Iran’s insistence on maintaining control over the Strait of Hormuz.

With diplomacy now in limbo and the ceasefire nearing expiration, analysts warn that the window for preventing a broader confrontation is rapidly closing. Both sides continue to exchange sharp rhetoric, with Iran asserting it possesses “new cards on the battlefield,” while the U.S. Maintains that military pressure will remain until Tehran verifiably abandons nuclear aspirations.
