Four South Korean fighter jets “precision” bombed a dummy target in the Yellow Sea on Tuesday, according to Seoul’s Joint Chiefs of Staff (JCS), in a show of force in response to North Korea’s launch of an intermediate-range ballistic missile (IRBM) earlier in the day.

U.S. F-16 fighter jets also practiced attack squadron flights alongside South Korean F-15K jets as part of the training on Tuesday, JCS said.
