Senior North Korean counterintelligence official believed to have defected
One of North Korea’s most senior intelligence officials, who played a major role in building Pyongyang’s nuclear weapons program, has disappeared and is believed to have defected to France or Britain, according to sources. South Korean media identified the missing official as “Mr. Kang”, and said he is a colonel in North Korea’s State Security Department (SSD), also known as Ministry of State Security. Mr. Kang, who is in his mid-50s, enjoyed a life of privilege in North Korea, because he is related to Kang Pan-sok (1892-1932), a leading North Korean communist activist and mother to the country’s late founder, Kim Il-sung.
According to South Korean reports, Kang was in charge of North Korea’s counter-espionage operations in Russia and Southeast Asia, including China. He is also believed to have facilitated secret visits to Pyongyang by foreign nuclear scientists, who helped build North Korea’s nuclear weapons program.
