SEOUL: North Korea celebrated the birth anniversary of late leader Kim Jong-Il on Sunday after promoting key military officials including the chief of its rocket unit, state media said. Kim Rak-Gyom, the commander of the Korean People’s Army (KPA) Strategic Rocket Force Command, was promoted to colonel general at the order of leader Kim Jong-Un, the Korean Central News Agency (KCNA) reported late Saturday. The unit is in charge of the country’s mid- and long-range missiles program. Dozens of other senior military officials were also promoted to the rank of lieutenant general and major general, the KCNA said. The latest round of military promotions—often announced on key political anniversaries—came as the North celebrated Jong-Il’s birthday. The country marks the birthdays of both late leaders—Jong-Il’s on February 16 and his father Kim Il-Sung’s on April 15—as major national holidays.
