Hyon Song-wol, a singer alleged to have been romantically involved with the North Korean leader, was arrested on August 17 on pornography charges.

Hyon, who performed with the Unhasu Orchestra was then machine gunned along with 11 others nine days later.

The families of those killed by the regime were made to watch their loved-ones’ executions before being sent to gulags.

“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,” claimed a source in South Korea’s Chosun Ilbo newspaper.

The Unhasu Orchestra’s patriotic songs had been popular in the country, with hits such as the much-loved song Excellent Horse-Like Lady.

Chosun Ilbo’s report claimed that the other 11 killed were also members of popular bands and orchestras.

It also claimed they were accused of making videos of them engaged in sexual acts and selling the videos.

Kim Jong-un’s wife Ri Sol-ju was also a member of the Orchestra and one theory posits that it was she who objected to the high profile of her husband’s ex girlfriend.

In 2012 Kim ordered the execution of a minister by mortar round.
