North Korea fired at least one anti-ship cruise missile earlier this month, a South Korean military official told reporters on Thursday, partially confirming an earlier report from a South Korean media organization that a test fire happened sometime around the U.S. Fourth of July holiday this year.

The missile test was not reported in North Korean state media earlier this month, nor by U.S. or ROK authorities at the time. Now, South Korea's Ministry of National Defense (MND) belatedly implied on Thursday that Seoul had in fact known about the July test fire.
