North Korea test-fired one of its most powerful long-range ballistic missiles on Monday, Seoul and Tokyo said, a day after the nuclear-armed country launched a short-range weapon into the Sea of Japan.

Japan's Defense Ministry said the weapon, believed to be an intercontinental ballistic missile, had flown for about 73 minutes before splashing down into waters outside the country's exclusive economic zone (EEZ), approximately 250 kilometers west of Hokkaido's Okushiri Island.

In Seoul, the South Korean Presidential Office "strongly condemned" what it said was the launch of a "solid-fueled ICBM," with President Yoon Suk-yeol ordering a joint response together with the U.S. and Japan by employing the countries' real-time missile information-sharing system.
