In 1977, 13-year-old Megumi Yokota vanished from the Japanese coastal city of Niigata on her way home from school. Twenty-five years later, North Korea admitted that its agents had snatched her away, along with 12 other Japanese citizens, in order to train its spies. In a groundbreaking diplomatic move, Pyongyang returned five of them in 2002, but not Megumi, claiming she had committed suicide. Her brothers Takuya and Tetsuya Yokota, who have spent the last 45 years waiting for answers, speak to FRANCE 24.
