In August 1950, 14-year-old Ahn Seung-choon was still asleep at home early one morning when her mother woke her up, screaming that her 17-year-old brother had been taken by North Korean soldiers.
"Someone took your brother, and you are still sleeping!" Ahn recalls her mother shouting. Her mother had tried to chase the boy and his abductors, but she had babies to take care of at home and couldn't follow them for long.
"After that day, we didn't hear anything about him," Ahn says 68 years later in Suwon, a city south of the capital Seoul.
