Trump said he had ordered envoys Steve Witkoff and Jared Kushner not to travel to Islamabad, where mediation efforts had been centered following the arrival of Iranian Foreign Minister Abbas Araghchi for talks with Pakistani officials.

Speaking before departing Florida and later in comments to Fox News, Trump said the revised Iranian offer failed to meet U.S. expectations and dismissed the value of sending negotiators for extended talks.“I’ve told my people a little while ago they were getting ready to leave, and I said, ‘Nope, you’re not making an 18-hour flight to go there,’” Trump said, according to Fox News.

“We have all the cards. They can call us anytime they want.”In a post on Truth Social, Trump added that there was “tremendous infighting and confusion” within Iran’s leadership and said, “Nobody knows who is in charge, including them.”

The cancellation dealt a setback to mediation efforts in Islamabad, where Araghchi had concluded meetings with Pakistani leaders without direct contact with U.S. representatives.

Araghchi described the visit as “very fruitful,” while Iranian President Masoud Pezeshkian told Pakistani Prime Minister Shehbaz Sharif that Tehran would not accept what he called “imposed negotiations” conducted under threats or blockade.

Iran urged Washington to remove operational restrictions, including measures affecting Iranian ports, while maintaining that it would not accept maximalist demands.“Principally, Iranian side will not accept maximalist demands,” an Iranian diplomatic source in Islamabad told Reuters.

Tensions remain elevated across the region despite a ceasefire currently in force after a conflict that began on Feb. 28 with U.S.-Israeli airstrikes on Iran. Tehran later launched retaliatory strikes against Israel, U.S. military bases and Gulf states, escalating fears of a broader regional war.

The standoff has also disrupted maritime traffic through the Strait of Hormuz, a critical global energy corridor, while U.S. restrictions on Iranian oil exports remain in place, pushing energy prices to multi-year highs and adding pressure to global inflation and growth.

In Israel, Prime Minister Benjamin Netanyahu ordered forces to strike Hezbollah targets in Lebanon “forcefully,” testing a fragile three-week ceasefire and underscoring the broader instability surrounding the negotiations.

White House press secretary Karoline Leavitt had said earlier that Washington had seen some progress from Iran in recent days and hoped for further movement over the weekend.Vice President JD Vance, who led an earlier unsuccessful round of indirect talks in Islamabad this month, had also been prepared to travel again if negotiations advanced.

Defense Secretary Pete Hegseth said Iran still had an opportunity to reach an agreement if it made verifiable commitments on its nuclear program.“All they have to do is abandon a nuclear weapon in meaningful and verifiable ways,” Hegseth said.

Iran’s foreign ministry later confirmed that no direct meeting with U.S. officials had been planned during Araghchi’s visit and said Tehran would instead convey its position through Pakistan as mediator.

In a telephone conversation, Lavrov stressed the importance of preventing a return to armed confrontation and reiterated that the conflict has no military solution, according to the ministry’s statement.

The call followed recent talks between the United States and Iran in Pakistan, which ended without agreement. Araqchi briefed Lavrov on the discussions, the ministry said, providing details of negotiations that failed to produce a settlement.

Russia has positioned itself as a potential mediator in the conflict, signaling willingness to engage diplomatically as tensions remain high despite a temporary ceasefire and ongoing international efforts to restart negotiations.
