Diplomatic efforts between the United States and Iran have ended in failure after 21 hours of negotiations in Islamabad failed to produce an agreement, leaving a fragile ceasefire in doubt.
The talks, led by U.S. Vice President JD Vance, broke down over key disputes including Iran’s nuclear programme and Washington’s demand for binding commitments to halt any potential development of nuclear weapons. U.S. officials said Iran refused to accept the proposed terms, while Iranian representatives accused the U.S. of making “excessive” and “unrealistic” demands.
The collapse of the discussions has cast uncertainty over a recently established two-week ceasefire aimed at reducing tensions in the region. Mediators from Pakistan urged both sides to maintain restraint and continue diplomatic engagement despite the breakdown.
There has been no confirmation of further talks, with Iranian officials indicating that no new negotiations are currently scheduled. The U.S. delegation has since returned home without a deal, though Washington has stated it remains open to future discussions if conditions are met.
The failure of the negotiations raises concerns about renewed escalation in a region already destabilised by months of conflict and heightened tensions over strategic waterways and energy routes.
