“A day after four Iranian boats harassed a destroyer in the Persian Gulf, a similar squad of vessels came after three more U.S. ships on Wednesday, according to a U.S. Navy spokesman. The destroyer Stout and the coastal patrol ships Tempest and Squall were all approached throughout the day by small boats, 5th Fleet spokesman Cmdr. Bill Urban told Navy Times, escalating to three warning shots fired, as Iranian paramilitaries seek more confrontations in the Persian Gulf.”
