The ex-girlfriend of North Korean leader Kim-Jong-un was one of a dozen people reportedly executed by a firing squad last week.
The South Korean newspaper Chosun Ilbo reports that singer Hyon Song-wol and 11 others had been arrested on August 17 for violating North Korea's laws against pornography and was executed three days later.
The paper reported that the condemned, all members of the performing groups Unhasu Orchestra and Wangjaesan Light Music Band, were accused of making videos of themselves having sex and selling the videos, which the paper reported were available in China.
"They were executed with machine guns while the key members of the Unhasu Orchestra, Wangjaesan Light Band and Moranbong Band as well as the families of the victims looked on," a source told the paper.
The source added that the victim's families appear to have all been sent to prison camps.
Kim Jong-un reportedly met Hyon Song-wol approximately 10 years ago, before he was married.
The relationship between the two is believed to have ended after interference from Kim's father, Kim Jong-il, though the two had been rumored to be having an affair. Kim Jong-un's wife, Ri Sol-ju, was also a member of the Unhasu Orchestra before their marriage. It is not clear if she had any role in the executions.
