Iran has signalled it has no plans to send negotiators to Islamabad for a new round of talks with the United States, casting fresh uncertainty over Pakistan’s efforts to host multiday negotiations less than 48 hours before a fragile ceasefire expires.

The announcement comes amid a sharp escalation in tensions, with Tehran accusing Washington of violating the truce through a naval blockade of the Strait of Hormuz and the seizure of an Iranian cargo vessel. Iranian officials described the interception as “armed piracy” and warned that continued pressure would undermine any prospect of meaningful diplomacy.

The development threatens to derail Pakistan’s push to convene a second round of negotiations aimed at extending the ceasefire and securing a temporary understanding between the two sides. Islamabad had been preparing for prolonged talks, hoping to broker a memorandum of understanding that could prolong the truce and create space for a broader settlement.

However, Iranian authorities have hardened their public stance, accusing the United States of inconsistent positions, excessive demands and bad faith. State media dismissed reports of imminent talks in Islamabad as inaccurate, suggesting there was “no clear prospect” for productive negotiations under current conditions.

The standoff has been exacerbated by statements from US President Donald Trump, who confirmed that American representatives were travelling to Pakistan while simultaneously threatening strikes on Iranian infrastructure if a deal is not reached. The rhetoric, coupled with military actions in the Gulf, has deepened mistrust between the two sides.

Despite the setback, Pakistani officials say they remain cautiously hopeful that diplomacy can still be revived. Islamabad has intensified engagement with both capitals in recent days, positioning itself as a key intermediary in the conflict. Yet officials privately acknowledge that the latest developments have significantly dimmed the prospects of immediate talks.

The ceasefire, agreed earlier this month after weeks of conflict, is due to expire within days. With core disputes — including Iran’s nuclear programme and control over strategic waterways — still unresolved, expectations for a comprehensive agreement remain low.
