A possible resumption of negotiations between the US and Iran in the capital of Pakistan.

The US and Iranian governments unleashed threats against each other yesterday, Monday, on the eve of the end of a two-week ceasefire they declared.

A source familiar with the matter in Washington assured Agence France-Presse that an American delegation would leave “soon” for Islamabad to hold talks with representatives of the Islamic Republic, without giving a specific date.

No official information was being circulated in Washington about the possible talks late last night, with the end of the April 8 ceasefire between the two states now on the horizon. The ultimatum expires “Wednesday night Washington time,” Donald Trump told Bloomberg news agency, calling “very unlikely” an extension of the truce. It will end, in theory, on Wednesday night into Thursday Tehran time.

J.D. Vance in Pakistan

According to an Axios report citing three U.S. sources, however, the U.S. vice president Jay Di Vance is expected to travel to Pakistan on Tuesday to participate in talks with Iran.

According to the US news website, Vance, who led the US delegation in the first round of talks, will arrive in Islamabad as part of the team from Washington, with the two-week-old ceasefire on the verge of ending.

Also expected to travel are Steve Whitcoff and Jared Kushner, who were also present last time.

No decision has been taken

“We do not accept to negotiate under threat and, over the past two weeks, we have been preparing to reveal new cards on the battlefield,” countered the speaker of the Iranian parliament, Mohammad Bayr Galibaf, via X.

Iran has “at this stage” not planned anything “for the next round of negotiations,” “no decision has been taken on this issue,” Foreign Ministry spokesman Esmail Baghaei told reporters in Tehran earlier, expressing his government’s doubts about Washington’s “seriousness.”

If US demands are not met before the ceasefire expires, “a lot of bombs will start exploding,” Donald Trump threatened, on PBS this time, after suggesting earlier this month that a “whole civilization”will be wiped out in Iran.

The US president insists that the blockade of Iranian ports will continue “as long as there is no ‘deal,'” as he put it via Truth Social, asserting that Iran has foregone revenues of “$500 million a day,” an amount it “cannot afford,” not even “in the short term.”

“At least 26 ships in the Iranian shadow fleet have bypassed the US blockade” since it was imposed last week, however, shipping affairs specialist website Lloyd’s List Intelligence pointed out yesterday.

“Threatening rhetoric”

For his part, Iranian diplomatic chief Abbas Araghchi yesterday Monday voiced fresh criticism and accusations against the US, without explicitly ruling out Tehran’s participation in a new round of negotiations.

“The provocations, threatening rhetoric and ongoing ceasefire violations by the US, particularly attacks on Iranian merchant ships, raise a major obstacle to the continuation of the diplomatic process,” Mr. Araghchi told Pakistan’s Foreign Minister Muhammad Ishaq Dar by telephone, Tasnim news agency reported.

“Iran will carefully weigh the circumstances and then decide which way to go,” he added.

Iran is ready to throw “new cards on the battlefield” if war resumes, warned the speaker of Iran’s parliament, Mohammad Bayr Galibaf. “We will not accept negotiating under threat and, over the past two weeks, we have been preparing to reveal new cards on the battlefield,” Mr. Galibaf said via X.
