US-Iran War News Live Updates: Iran sets new Strait of Hormuz rules, requires vessel coordination and permits
Iran and the United States continue to exchange warnings even as diplomatic channels remain active through Pakistan-mediated talks aimed at ending the ongoing conflict.

Tehran has demanded sanctions relief, release of frozen assets and an end to the American blockade on Iranian ports as part of any agreement.
