President Donald Trump said the U.S. Navy will swiftly begin a blockade of ships entering or leaving the Strait of Hormuz after U.S.-Iran ceasefire talks in Pakistan ended without an agreement. U.S. Central Command announced that it will blockade all Iranian ports beginning Monday at 10 a.m. EDT, or 5:30 p.m. in Iran. CENTCOM said the blockade will be “enforced impartially against vessels of all nations.” It said it would still allow ships traveling between non-Iranian ports to transit the Strait of Hormuz. Earlier in the day, the United States and Iran ended 21 hours of face-to-face talks in Islamabad without reaching a deal.
