According to the Financial Times, over the past several months U.S. military divers, unmanned vessels and specialized submersibles carried out mine-clearing operations in the Strait of Hormuz at night. The International Maritime Organization said Iran laid about 80 mines; Trump announced that all of them have been cleared or detonated, and the U.S. military confirmed this. Iran rejected the U.S. claims, and U.S. Central Command denied rumors that a tanker struck a mine.
