President Donald Trump announced an indefinite extension of the ceasefire in the conflict with Iran, saying he acted at Pakistan’s request to give mediators more time to organize another round of direct talks. He said the move came hours before the truce was due to expire while Pakistani facilitators awaited a “unified proposal” from Tehran.
The extension prevented an immediate return to fighting, but major differences remain. A planned trip to Pakistan by U.S. negotiator Vice President J.D. Vance was postponed and the U.S. maritime blockade of Iran remains in force.
Signs of willingness, but doubts about participation
Regional officials told the Associated Press that both Washington and Tehran have signaled readiness to resume negotiations, and Pakistani mediators reported confirmation that top envoys—Vance for the U.S. and Iran’s parliament speaker Mohammad Bagher Ghalibaf—would lead their delegations. Yet Iran’s foreign ministry spokesman, Esmail Baghaei, later said there was no final decision to attend, citing “contradictory messages” and “unacceptable actions” by the Americans, notably the naval blockade.
With a midnight GMT deadline looming, Vance canceled his trip as Pakistani leaders tried to salvage the initiative. Trump extended the truce indefinitely, saying he had done so at Pakistan’s request and blaming Iran’s “seriously fractured” leadership for the uncertainty. He also reiterated that the U.S. blockade would continue.
Ongoing flashpoints: Strait of Hormuz, naval incidents and the blockade
Even if talks go ahead, profound disputes remain over the status of the Strait of Hormuz, Iran’s nuclear program and the U.S. blockade. Iran has attacked vessels in the strait, and U.S. forces recently boarded an Iranian ship that tried to challenge the blockade, highlighting the volatility that persists.
The Strait of Hormuz — a strategic chokepoint through which roughly 20% of the world’s oil and natural gas transits — has been effectively disrupted by Iranian attacks and concerns about mines. Reports say Iran has been charging as much as $2 million per ship for passage. Restoring safe, commercial transit is a central bargaining issue and a major source of leverage for Tehran as countries face energy rationing and jet-fuel shortages.
The U.S.-led blockade has prevented ships from calling at Iranian ports. Iran has condemned U.S. boarding operations as “piracy” and violations of international law.
How the fighting and truce evolved
The U.S. and Israel launched their campaign on February 28, triggering a six-week conflict that pushed oil prices up and unsettled global markets. The current truce among Iran, Israel and the United States began on April 8 after a series of U.S.-imposed deadlines. A separate ceasefire between Israel and the Iran-backed Hezbollah in Lebanon took effect more recently; both ceasefires have largely held so far.
An earlier U.S.-Iran negotiating session in Pakistan on April 11–12 was the highest-level contact between the two countries since 1979 but ended without agreement. Pakistani officials have prepared for another similar meeting, suggesting a further diplomatic effort could be imminent.
Iran’s nuclear material and competing demands
All of Iran’s highly enriched uranium is believed to remain inside the country, likely stored at enrichment sites that U.S. strikes damaged during a 12-day campaign last June. Iran has not resumed enrichment since those strikes but maintains it reserves the right to enrich for peaceful purposes and denies seeking nuclear weapons. The U.S. and Israel insist Iran fully dismantle its nuclear program and hand over its stockpile; Tehran rejected those demands in a 10-point proposal to end the war.
