SEOUL (AFP) - A South Korean court handed down a four-year jail sentence Wednesday to a convicted North Korean spy who was involved in a bid to maim the eldest son of the North’s late leader Kim Jong-Il. The unidentified spy had arrived in South Korea in March posing as a refugee who had fled the communist North via China, the court heard. Under interrogation by security authorities, the man confessed to being part of a plot to stage a hit-and-run car accident in China in 2010 targeting Kim’s eldest son, Kim Jong-Nam. Kim Jong-Nam fell out of favour with his father following a botched attempt in 2001 to secretly enter Japan using a fake passport and visit Disneyland. He has since lived in virtual exile, mainly in the Chinese territory of Macau.
