Kim Jong Un Tests Cluster-Bomb Missiles from Sinpo

North Korea launched five upgraded Hwasong-11LA short-range, surface-to-surface tactical ballistic missiles from the coastal city of Sinpo on April 19, 2026. Kim Jong Un oversaw the tests, which evaluated new cluster bomb and fragmentation mine warheads targeting an island approximately 136 to 140 kilometers away. The missiles struck an area of roughly 31 to 32 acres, a result Kim described as having weighty significance for boosting high-density striking capability.

This event marked Pyongyang's seventh ballistic missile launch of the year and its fourth in April. In response, South Korea's presidential office convened an emergency National Security Council meeting, and Japan activated top-tier crisis management protocols. Japanese Prime Minister Sanae Takaichi stated the missiles likely fell outside Japan's exclusive economic zone. South Korean and U.S. intelligence authorities tracked the projectiles and shared data to determine if the launch involved a submarine-launched ballistic missile.

The escalation follows warnings from International Atomic Energy Agency Director General Rafael Grossi regarding a rapid increase in nuclear manufacturing activities and the possible discovery of a new uranium enrichment facility. The tests occurred as South Korean President Lee Jae Myung prepared for diplomatic visits to India and Vietnam, and shortly before a planned mid-May summit between U.S. President Donald Trump and Chinese President Xi Jinping. While the Government of North Korea maintains the tests are a sovereign right to self-defense, the regional coalition condemned the launches as violations of United Nations Security Council resolutions.
