Pakistan presses ahead with preparations for Iran-US talks even with Tehran’s participation unclear

Pakistan is preparing for a second round of U.S.-Iran negotiations in Islamabad amid an uncertain ceasefire. Tensions remain high as U.S. President Donald Trump threatens military action if no agreement is reached by Wednesday, while Iran's chief negotiator claims Tehran has 'new cards on the battlefield.' The U.S. has blockaded Iranian ports to pressure Iran over control of the Strait of Hormuz, a critical shipping lane.
