U.S. military blocks all Iranian ports as Iran takes aim at U.S. allies

VIDEO: The U.S. military has vowed to blockade all Iranian ports starting Monday. That’s part of the efforts to force Tehran into agreeing to open the crucial Strait of Hormuz and accepting a peace deal. Iran responded with threats on all ports in the Persian Gulf and the Gulf of Oman, taking aim at U.S.-allied countries. That set the stage for an extraordinary showdown that contains serious risks for the global economy and raises the specter that the current ceasefire could collapse and the war could resume.
