100 North Korean defectors caught by secret police have 'vanished': Rights group

Over 100 North Koreans have "vanished" after being caught by secret police while trying to defect from the country or even for trying to call relatives in South Korea, a rights group said. Thirty percent of the disappearances happened since Kim Jong-un took power. Tens of thousands of North Koreans have defected since Korean War ended in 1953.
