(CNN)The Navy destroyer USS Mason fired countermeasures in the Red Sea on
Saturday after it detected what it believed were incoming missiles.
Officials Saturday night were uncertain about what exactly happened, if
there were multiple incoming missiles or if there was a malfunction with the
radar detection system on the destroyer.
"We are aware of the reports and we are assessing the situation. All of our
ships and crews are safe and unharmed," one US defense official told CNN.
The USS Nitze and the USS Ponce were sailing nearby.
