North Korea on Thursday released a video in which a pair of parents wept and demanded the South Korea to return their daughter who is one of the 12 waitresses that Pyongyang insists were kidnapped by South Korean agents.

The video is published on North Korea’s propaganda website Uriminzokkiri. In the video, the parents shed tears, shouted in desperation, and demanded South Korea to “return” their daughter Gyong-A.

"Gyong-A, resist strongly until you return to the bosom of our Marshal (Kim Jong Un)," the father was quoted as saying by AFP. The mother called Geun-Hye the "devil", saying that even if they can revenge by booming the Blue House (South Korea's presidential palace) to pieces, their grief would not be appeased.

Titled "Interview with families of kidnapped girls", the video had a serial number one -- an indication that the North will possibly upload similar videos with other parents in the future.

Seoul's Unification Ministry said that 13 people- 12 waitresses and one manager from the DPRK working in an overseas restaurant have defected to South Korea on April 8, 2016. South Korean media said this marked the first time that a group of DPRK citizens working at the same overseas restaurant defected to South Korea.
