(CNN) -- The testimonies, one after another, have been damning, disturbing and, at points, excruciating.
A North Korean prison camp survivor told of a pregnant woman in a condition of near-starvation who gave birth to a baby -- a new life born against all odds in a grim camp. A security agent heard the baby's cries and beat the mother as a punishment.
She begged him to let her keep the baby, but he kept beating her.
With shaking hands, the mother was forced to pick up her newborn and put the baby face down in water until the cries stopped and a water bubble formed from the newborn's mouth.
