Speaking before boarding Air Force Two, Vance said Washington was open to constructive negotiations but warned that progress would depend on Tehran’s willingness to engage in good faith.

“We’re going to try to have a positive negotiation,” Vance told reporters. “If the Iranians are willing to negotiate in good faith, we’re certainly willing to extend the open hand.”

The diplomatic effort comes amid heightened tensions following a two-week ceasefire agreement that has been repeatedly tested by mutual accusations of non-compliance.

Pakistan is hosting the talks as part of ongoing international efforts to prevent further escalation between Washington and Tehran, with the outcome seen as critical to maintaining regional stability.

In a written statement broadcast on Hezbollah’s Al-Manar television, Qassem said the group would not accept a return to prior arrangements and called on Lebanese officials to take a firmer stance in upcoming talks.

His remarks followed Israeli strikes earlier this week that he described as “bloody criminality,” referring to attacks on Wednesday that reportedly killed more than 300 people in Lebanon.

The comments come as Beirut and Tel Aviv are preparing to begin negotiations in the United States, part of ongoing diplomatic efforts to address escalating tensions between the two countries.

During the call, the ministers reviewed recent developments and discussed ways to reduce tensions and restore regional security and stability, according to the statement posted on X.

The contact comes amid a fragile ceasefire announced earlier this week following heightened hostilities that saw Iran launch strikes against Gulf states, including Saudi Arabia, in response to Israeli and U.S. military actions.

The exchange signals a potential diplomatic opening between Riyadh and Tehran at a time of sustained regional volatility, with multiple fronts of conflict continuing despite the truce.

“All U.S. Ships, Aircraft, and Military Personnel, with additional Ammunition, Weaponry will remain in place in, and around, Iran, until such time as the REAL AGREEMENT reached is fully complied with,” Trump said.He added that any failure to adhere to the terms would trigger a forceful response.

“If for any reason it is not, which is highly unlikely, then the ‘Shootin’ Starts,’ bigger, and better, and stronger than anyone has ever seen before,” he said.The remarks come amid a fragile ceasefire between the United States and Iran following weeks of heightened regional tensions.

The scope and durability of the truce remain uncertain as both sides continue to differ over key provisions, particularly Iran’s nuclear program.

Earlier on Wednesday, Iran said it would be “unreasonable” to proceed with negotiations toward a permanent peace agreement with Washington following intensified Israeli strikes on Lebanon, which Tehran cited as a destabilizing factor.

Significant gaps remain between the two sides on uranium enrichment. Trump has said Iran agreed to halt enrichment activities, while Iran’s parliament speaker, Mohammed Bager Qalibaf, has maintained that Tehran retains the right to continue enrichment under the ceasefire terms.

Trump also reiterated that preventing Iran from acquiring nuclear weapons remains a central objective of the agreement and said the Strait of Hormuz would remain open and secure.

According to the report, which cited four U.S., Israeli and regional sources, the proposed arrangement would begin with a temporary ceasefire lasting 45 days, during which negotiators would seek to reach a permanent agreement to end the war.

A second phase would focus on finalizing terms for a comprehensive settlement.The report said the ceasefire period could be extended if additional time is needed to conclude negotiations.

Reuters could not independently verify the Axios report, and neither the White House nor the U.S. State Department immediately responded to requests for comment.

The development comes as tensions remain high, with U.S. President Donald Trump reiterating a deadline for Iran to reopen the Strait of Hormuz or face potential strikes on critical infrastructure.

In an interview with the Wall Street Journal, Trump said the deadline would expire on Tuesday evening.

Writing in Foreign Affairs, Zarif said Iran should offer to limit its nuclear program and reopen the Strait of Hormuz in exchange for a comprehensive lifting of U.S. sanctions, a proposal he said Washington had previously rejected but might now consider under changed circumstances.

The remarks come as the United States has put forward a 15-point ceasefire framework that includes restoring maritime access through the Strait of Hormuz, though there has been no indication of progress in negotiations.

Zarif, who played a central role in negotiating the 2015 nuclear agreement, no longer holds an official government position but remains an influential figure. Analysts note that such proposals are unlikely to be published without at least informal alignment with senior leadership in Tehran.

Iranian officials have repeatedly pointed to past instances in which negotiations with Washington coincided with military action, including the current conflict, as a source of distrust.

Zarif also criticized previous U.S. negotiating representatives, including Jared Kushner, questioning their expertise in geopolitics and nuclear policy.

The proposal underscores tentative signals of diplomatic maneuvering amid ongoing hostilities, even as military exchanges and tensions in the region continue.

According to the report, some officials in the White House view Ghalibaf as a pragmatic figure who could engage in negotiations with Washington as the conflict with Iran enters a new phase.

The report said discussions remain preliminary and are being conducted quietly within the administration. Ghalibaf is seen by certain policymakers as a figure capable of navigating Iran’s political structure while maintaining enough authority to enter into talks with the United States.

There was no immediate comment from the White House on the report.Context of rising tensionsThe deliberations come amid escalating hostilities between the United States and Iran, including ongoing military exchanges and heightened regional instability.

The conflict has drawn in multiple actors across the Middle East, increasing the risk of broader escalation.Uncertainty over Tehran’s stanceIt remains unclear how such considerations would be received in Tehran.

Iranian officials have publicly rejected claims of engagement with Washington, with Ghalibaf himself recently denying that any negotiations with the United States have taken place.

The Israeli military said the incoming missiles activated warning systems across several regions, with interceptions heard over Tel Aviv. In northern Israel, residential buildings were damaged by debris from intercepted projectiles.

No fatalities were reported.The escalation came hours after Trump said he would delay, by five days, a planned strike on Iran’s power grid, citing what he described as “very good and productive” discussions aimed at resolving hostilities in the Middle East.

Iranian officials moved swiftly to counter Trump’s statement. Parliament Speaker Mohammad Baqer Qalibaf said no talks had taken place, calling the U.S. claims “fake news” intended to manipulate financial and oil markets and deflect from mounting geopolitical pressure.

According to sources familiar with the matter, Qalibaf had been identified as a key interlocutor in the purported exchanges. However, his public denial cast doubt on the existence of any backchannel diplomacy.

Iran’s Revolutionary Guards said they were continuing operations, including attacks on U.S. targets, and described Trump’s remarks as “psychological operations” with no bearing on Tehran’s military posture.

Global markets reacted sharply to the shifting narrative. Trump’s announcement of a delay in military action had initially buoyed investor sentiment, pushing share prices higher and driving oil below the $100-per-barrel mark after earlier volatility tied to threats of escalation.

By Tuesday, those gains appeared at risk as renewed hostilities and Iran’s rejection of negotiations reintroduced uncertainty into energy markets and broader risk sentiment.

The diplomatic confusion follows Trump’s weekend ultimatum demanding that Iran reopen the Strait of Hormuz within 48 hours. The strategic waterway carries roughly one-fifth of the world’s oil and liquefied natural gas, making it a critical chokepoint for global energy supply.

Iran has not indicated any shift in its stance on the strait, and the continued exchange of threats and military actions has heightened concerns over potential disruptions to energy flows and regional stability.
