Pakistani Foreign Minister Ishaq Dar convened a second round of proximity talks in Islamabad on Tuesday, bringing together Iranian and American diplomatic representatives through intermediaries in what officials described as the most substantive engagement between the two sides since tensions over Iran's nuclear programme escalated sharply in early 2026. The talks, held at the Pakistani foreign ministry, involved senior diplomats from both nations communicating indirectly through Pakistani and Omani mediators.

Iran's foreign ministry issued a statement Tuesday morning reiterating its accusation that US military planners had drafted operational blueprints for a ground incursion, a charge the Pentagon flatly denied. A US State Department spokesperson confirmed that American diplomats were 'engaged in the process' but insisted Washington had 'not authorised any offensive ground operations' and was committed to a diplomatic resolution, provided Iran halted uranium enrichment above 60 percent purity.

The Pakistani initiative, publicly backed by China and Turkey, has gained quiet support from Gulf states concerned about the economic consequences of a broader military conflict. Saudi Arabia and the UAE both sent senior envoys to Islamabad ahead of Tuesday's session, according to Pakistani government sources. The involvement of Riyadh, which has its own complex relationship with Tehran, was seen by analysts as a sign that regional stakeholders are applying pressure on both sides to avoid escalation.

Iranian state media reported that Supreme Leader Ali Khamenei had authorised the foreign ministry to 'explore diplomatic channels without preconditions,' a formulation that represented a subtle shift from Tehran's earlier insistence that sanctions relief precede any substantive discussions. Analysts at the International Crisis Group cautioned that the gap between the parties remains wide but noted that the mere continuation of talks reduces the immediate risk of miscalculation.

Markets and energy observers are closely monitoring the outcome. Brent crude remained elevated above $96 per barrel on Tuesday, reflecting persistent anxiety over Strait of Hormuz access. New Zealand Prime Minister Christopher Luxon, whose country faces fuel supply vulnerabilities linked to the disruption, said Islamabad's mediation effort was 'welcome and necessary,' adding that Wellington had conveyed its concerns directly to both Washington and Gulf partners through diplomatic channels.
