Two Pakistani officials, speaking on condition of anonymity, said Islamabad has offered to again facilitate negotiations, although the final venue would depend on whether Washington or Tehran request an alternative location.

They described the initial round of talks as part of an ongoing diplomatic process rather than a one-off effort.The proposal follows marathon negotiations held on April 12 that ended without a breakthrough but were marked by what U.S. Vice President JD Vance described as “some progress,” particularly on Washington’s demands regarding Iran’s nuclear program.

In an interview with Fox News, Vance said Iranian negotiators had moved closer to U.S. positions on the removal of nuclear material and mechanisms to prevent future uranium enrichment, but were unable to finalize a deal, suggesting decisions may require approval from authorities in Tehran.

“There really is, I think, a grand deal to be had here,” Vance said, adding that the next step rests with Iran.The White House did not confirm whether preparations for a second round are underway. Press Secretary Karoline Leavitt reiterated that U.S. negotiating positions remain unchanged and pointed to increased pressure on Iran following the implementation of a U.S. naval blockade.

Multiple sources familiar with the discussions said both sides are considering further in-person talks aimed at reaching an agreement before the ceasefire expires next week. While Islamabad remains a leading candidate to host the meeting, other locations such as Geneva are also under consideration, with timing still undecided but potentially within days.

A diplomat involved in mediation efforts said there is growing alignment on holding another round, though details on the level of representation and agenda remain unresolved.U.S. President Donald Trump said earlier that Iran had reached out seeking a deal, underscoring continued engagement between the two sides even as tensions persist.

Trump told reporters at the White House that U.S. officials were engaged with “the right people” in Iran and suggested Tehran was eager to reach an agreement.

A source familiar with the matter confirmed that Washington had transmitted a multi-point proposal aimed at halting the conflict, now in its fourth week following U.S. and Israeli strikes launched on February 28.Iranian authorities denied that direct negotiations were underway.

Parliament Speaker Mohammad Baqer Qalibaf dismissed reports of talks as “fake news,” underscoring persistent gaps between public positions and diplomatic signals.

According to media reports cited by regional outlets, the U.S. proposal includes provisions for dismantling Iran’s nuclear program, ending support for proxy groups, and reopening the Strait of Hormuz. A month-long ceasefire has also been discussed to facilitate negotiations, though no official confirmation of those terms has been issued by Washington.

Trump said Iran had made a “valuable concession” linked to non-nuclear energy and maritime transit through the Strait of Hormuz, a critical chokepoint through which roughly 20% of global oil supply typically flows. He did not provide details.

Iran informed the United Nations Security Council and the International Maritime Organization that non-hostile vessels could transit the strait if coordinated with Iranian authorities, according to a note seen by Reuters. The waterway has effectively been shut since the outbreak of hostilities, triggering a sharp global energy supply disruption.

Despite diplomatic signals, military activity has continued on all sides. Two sources said the United States is preparing to deploy thousands of troops from the Army’s 82nd Airborne Division to the Middle East, adding to approximately 50,000 U.S. personnel already stationed in the region.

The deployment would accelerate a broader military buildup, heightening concerns among analysts and regional actors that the conflict could become prolonged even as negotiations proceed.

Pakistan’s Prime Minister Shehbaz Sharif said his government was willing to host talks between Washington and Tehran, expressing support for dialogue aimed at achieving a comprehensive settlement.

A Pakistani government source said discussions about a potential meeting were at an advanced stage, though no agreement had been finalized.Pakistan maintains longstanding ties with Iran and has recently strengthened engagement with the United States, positioning itself as a potential intermediary.

The latest developments come a day after Trump delayed threatened strikes on Iranian power infrastructure, citing “productive” discussions, while Oman, which has acted as a mediator, previously indicated that progress had been made in earlier negotiations before the outbreak of conflict.

Sharif, writing on social media platform X, said Pakistan would be “ready and honoured” to facilitate “meaningful and conclusive talks” for a comprehensive settlement, subject to agreement by Washington and Tehran.

His statement comes as the war, involving U.S. and Israeli strikes on Iran and retaliatory attacks, entered its fourth week.Trump said on Monday that U.S. officials had engaged in “very good and productive” discussions with Iran over a “complete and total resolution of hostilities in the Middle East.”

He added that talks began on Sunday and continued into Monday, involving Special Envoy Steve Witkoff and adviser Jared Kushner.

Iranian parliament speaker Mohammad Baqer Qalibaf rejected the U.S. account, saying no talks had taken place and describing reports of negotiations as “fake news,” according to Iranian state-linked statements and sources familiar with the matter.

The divergence underscores the opacity surrounding diplomatic efforts as fighting continues across the region.

The United States and Israel launched strikes on Iran on February 28, citing a lack of progress in negotiations over Tehran’s nuclear programme. Mediator Oman had previously indicated that significant advances had been made in earlier discussions.

Since the strikes, Iran has responded with missile attacks and expanded its actions beyond Israeli territory, targeting countries hosting U.S. bases and striking Gulf energy infrastructure.

The conflict has disrupted global energy markets, with Iran effectively closing the Strait of Hormuz, a critical maritime route through which roughly one-fifth of the world’s oil and liquefied natural gas supplies transit.

The escalation has heightened concerns over supply stability and increased geopolitical risk across the Middle East, prompting renewed international calls for de-escalation through diplomatic channels.
