The destroyer USS Mason fired defensive countermeasures in response to what may have been incoming missiles, a defense official said .

U.S. officials had said earlier Sunday that the Mason had come under attack from two inbound missiles that originated in Houthi-controlled territory in Yemen.

According to one U.S. official, an initial report indicated that the destroyer had deployed defensive missiles, which resulted in the interception of one of the missiles(官话非常慎重而保守,就是不直说「这枚反舰导弹被击落」,看来后续评估确认之前官话就是必须这么保守), and that the other may have fallen into the sea. It now appears the destroyer fired missiles at what may have been incoming missiles.
The "post-event assessment" will determine what actually occurred Saturday, the official said.

In the earlier attacks, three missiles fired at the USS Mason from Houthi-controlled territory in Yemen all fell into the sea. It remained unclear whether two of them fell on their own into the sea or because of the defensive countermeasures used by the destroyer's crew.
