CAIRO (AP) — Pakistan’s army chief has arrived for talks in Tehran in the latest diplomatic move to ease tensions in the region and arrange a second round of negotiations between the United States and Iran. That’s according to the Pakistani military, which said Wednesday that the delegation included the country’s interior minister and other senior security officials. The military said the visit was “part of the ongoing mediation efforts,” but gave no further details. Pakistan has emerged as a key mediator in the conflict. Meanwhile, U.S. Treasury Secretary Scott Bessent warned that the U.S. will ramp up its infliction of economic pain on Iran. Bessent said the effort would be the “financial equivalent” of a bombing campaign.
