US-Iran nuclear talks in Pakistan collapse without agreement on sanctions, Hormuz

Marathon negotiations between the United States and Iran in Islamabad ended Sunday without resolving disagreements over nuclear programs, Strait of Hormuz shipping access, and sanctions relief, according to officials from both nations. The failure to reach compromise on these core issues marks a setback in diplomatic efforts to de-escalate decades of US-Iran tensions. The breakdown affects global oil markets and regional stability, as the Strait of Hormuz handles roughly one-third of world seaborne petroleum trade. Both sides have signaled willingness to resume talks, though no date has been set.
