South Korea’s Joint Chiefs of Staff (JCS) announced detection of the launch in real time on Thursday morning, saying multiple missiles flew around 223 miles (360 km). North Korea also did not disclose the precise number of rockets fired but showed Kim Jong Un looking at a screen with four individual target screens next to images of them striking a commonly targeted rocky island off the northeast coast. NK News analysis of state media photos and satellite imagery suggests the launch took place from a highway near the Majang-ri missile base south of Pyongyang on the border of Junghwa and Sangwon counties, 228 miles (367 km) from the target island.
