South Korea imposed sanctions on eight North Koreans linked to nuclear and missile development through arms trade, cyberattacks and other illicit activities, Seoul's foreign ministry said on Wednesday. The sanctions came days after North Korea fired a new intercontinental ballistic missile (ICBM), which South Korea and the United States strongly condemned as a grave violation of UN Security Council resolutions. South Korea has blacklisted 83 individuals and 53 entities related to North Korea's weapons programmes since October 2022.
