Members of the North Korean cheerleading squad that charmed Winter Olympics viewers are being forced into sex slavery by the country’s top politicians, a defector from the country has said.

“North Korea’s art troupe came here and performed with dances and songs, and it might seem like a fancy show on the outside,” Lee So-yeon, who was a musician in the North Korean military until she fled in 2008, told Bloomberg.

“But not only do they have to be in charge of promoting Kim Jong-un’s propaganda, they also have to go to parties and provide sexual services.”

Lee said that the parties are held “every day” by members of the Central Politburo, and “even if they don’t want this, they have to serve with their bodies, like a human rights infringement.

“The women there, when they attend, they have to undress. They’re asked to undress, like objects. That’s the physical pain they have to go through.”
