On 30 May 2024, the North Korean military test-fired suspected short-range ballistic missiles from the Sunan area, located approximately 20 km (13 mi) north of the capital Pyongyang, into the Sea of Japan. According to South Korea’s Joint Chiefs of Staff, approximately 10 projectiles that were launched from Sunan traveled about 350 km (215 mi) before falling into the sea. Japan’s coast guard issued a maritime safety advisory and urged vessels to exercise caution if any fallen objects were found. Japanese authorities believe the projectiles landed outside of Japan’s exclusive economic zone. The launch followed North Korea’s recent release of approximately 260 balloons containing waste and fecal matter into South Korea.
