Reuters reports that “a U.S. Navy destroyer fired three warning shots at four Iranian fast-attack vessels after they closed in at a high rate of speed near the Strait of Hormuz, two U.S. defense officials told Reuters on Monday.”

“The incident, which occurred Sunday and was first reported by Reuters, comes as U.S. President-elect Donald Trump prepares to take office on Jan. 20. In September, Trump vowed that any Iranian vessels that harass the U.S. Navy in the Gulf would be ‘shot out of the water.'”

“The officials, speaking on the condition of anonymity, said the USS Mahan established radio communication with the Islamic Revolutionary Guard Corps boats but they did not respond to requests to slow down and continued asking the Mahan questions.”
