Kim, 70, died on December 17 of a heart attack as a result of mental and physical strain while on a domestic train trip, the official Korean Central News Agency said. Kim probably had a stroke in August 2008 and may have also contracted pancreatic cancer, according to South Korean news reports.
The son of Kim Il Sung, North Korea’s founder, Kim was a chain-smoker and ruled for 17 years after coming to power in July 1994 and resisted opening up to the outside world in order to protect his regime. The likely succession of his little-known third son, Jong Un, threatens to trigger a dangerous period for the Korean peninsula, where 1.7 million troops from the two Koreas and the US square off every day.
