US Vice President JD Vance has been in direct contact “all night long” with Iranian Foreign Minister Abbas Araghchi through Pakistani mediators, as intense backchannel efforts continue to broker an end to the escalating US-Iran conflict, Reuters reports.
A source familiar with the negotiations told Reuters that Pakistan’s army chief, Field Marshal Asim Munir, facilitated the overnight communications involving Vance, US special envoy Steve Witkoff, and Araghchi.
The flurry of activity comes amid a proposed two-phase peace plan that could see an immediate ceasefire and the reopening of the strategically vital Strait of Hormuz, followed by a more comprehensive agreement within 15 to 20 days.
Under the framework, informally dubbed the “Islamabad Accord,” Iran would be required to lift its blockade on the strait – a critical artery carrying about one-fifth of global seaborne oil – in exchange for a halt in US strikes and potential sanctions relief.
The talks reflect the growing role of the US vice president in diplomatic efforts, with President Donald Trump reportedly directing Vance to convey both openness to a ceasefire – provided key American demands are met – and a “stern message” warning of increasing pressure on Tehran if no deal is reached.
Pakistan has emerged as a central intermediary between Washington and Tehran, alongside efforts involving Egypt and Turkey. The overnight contacts highlight the urgency as Trump has set a tight deadline for progress, with threats of further military action looming.
Neither the White House nor Iranian officials have issued official statements on the latest round of communications.
The developments come as the month-long conflict has disrupted global energy markets and raised fears of a wider regional war. Analysts caution that deep mistrust on both sides, coupled with Iran’s insistence on strong security guarantees, could complicate any breakthrough.
