ISTANBUL   North Korea on Friday said it fired an “ultimate version” of the intercontinental ballistic missile (ICBM), the Hwasongpho-19. The South Korean military confirmed that the ICBM missile fired early Thursday was the “largest long-range missile yet” produced by Pyongyang. In response, Seoul imposed sanctions on four North Korean entities and 11 individuals, including a China-based diplomat Choe Chol-min, for his role in procuring ballistic missile components and other dual-use items.
