Kim Seong-Min, a prominent North Korean defector who used radio broadcasts, USB sticks and a network of sources in the secretive country to inform the North Korean public about the truth of their authoritarian government, has died. He was 63. Kim, founder of the Seoul-based Free North Korea Radio, was pronounced dead at a Seoul hospital on Friday, years after fighting a lung cancer which recently spread to his liver, his former colleagues said. The former North Korean army captain, who arrived in South Korea in 1999, began shortwave radio broadcasts into North Korea — where most of people have no official access to foreign news — in 2005.
