CNN: ........In one radio transmission, the Iranians told the U.S. Navy: "I am coming at you. You will explode in a couple of minutes," the U.S. military officials told CNN.
When the U.S. ships heard that radio transmission, they manned their gun positions and officers were "in the process" of giving the order to fire when the Iranians abruptly turned away, the U.S. officials said.....
One of the Iranian ships had been dropping white boxes into the water in front of the U.S. ships, the officials told CNN.
