Nuclear-armed North Korea fired an apparent ballistic missile Sunday morning, Japan’s Defense Ministry said, as the world remains fixated on Ukraine and the Russian invasion of its neighbor.

Defense Minister Nobuo Kishi said North Korea launched at least one missile that was believed had traveled about 300 kilometers into the Sea of Japan, hitting a maximum altitude of 600 km. Kishi said the missile did not land in Japan's exclusive economic zone, which extends 200 nautical miles (370 km) from its coast.

Kishi called the launch "a threat to the peace and security of Japan, the region, and the international community" and an "unacceptable" violation of U.N. Security Council resolutions as the world grapples with the response to Russia's invasion of Ukraine.
