Pakistan has invited Iran's parliament speaker Mohammad Bagher Ghalibaf and Foreign Minister Seyyed Abbas Araghchi to Islamabad for urgent talks on regional developments, with Tehran formally designating Pakistan as its primary mediator in discussions with Washington. The invitations, delivered in Tehran late Monday, came roughly 36 hours after US President Donald Trump announced he had called off imminent strikes against Iran following appeals from regional allies including Saudi Arabia, the UAE, and Qatar. Trump nonetheless maintained an aggressive posture, warning Iran of "decapitation" if a deal is not reached, while Iran denied that formal negotiations with the US were underway — a dispute that underscores the fragility of diplomatic efforts to defuse one of the region's most volatile standoffs.
