North Korea appears to have used newly built targets on an island off the west coast during a missile test on Monday, according to NK Pro analysis of satellite imagery, likely in an attempt to demonstrate the missile’s accuracy to adversaries or potential buyers like Russia.

South Korea’s Joint Chiefs of Staff (JCS) announced on Monday afternoon that North Korea launched “multiple” close-range ballistic missiles (CRBMs) at around 1:50 p.m. KST from south of the capital in Hwangju County. An unspecified number of missiles reportedly flew 37 to 62 miles (60 to 100 kilometers) west toward the Yellow Sea
