According to reports Kim Jong-un's ex- girlfriend, Hyon-Song-wol, a singer was allegedly executed along with a dozen of well known North Korean performers, for violating laws against pornography.
Hyon was arrested along with orthers for violating pornographic laws and were executed three days later in public. "They were executed with machine guns while key members of the Unhasu Orchestra, Wangjaesan Light Band and Moranbong band as the families of the victims were forced to watch," a Chinese paper reported.
Kim and Hyon met about ten years back when neither of them were married. But later on Kim was asked to break off his relationship with Hyon, by his father. Both of them then got married; Kim got married to Ri-Sol-ju, an ex member of the Unhasu Orchestra, whereas Hyon got married to a soldier.
Nothing is clear as to who is behind the killings of the orchestra and band members.
