"I saw awful things in Pyongyang".
The Sun reports Hee Yeon Lim, 26, the daughter of a high-ranking soldier from Pyongyang, fled to South Korea a year ago and has told of the horrors she witnessed while part of the secretive Kim regime's inner circle.
A defector from North Korea has described the shocking brutality she witnessed from inside Kim Jong-un's regime.
The musicians were killed over allegedly making a pornographic video, and Hee said 10,000 people witnessed their execution.
"The musicians were brought out, tied up, hooded and apparently gagged, so they could not make a noise, not beg for mercy or scream".
Hee Yeon told how she and her classmates were ordered out of their classrooms in the middle of the day by soldiers who took them to a stadium at the city's Military Academy.
"They were lashed to the end of anti-aircraft guns", she said.
She went on: "A gun was sacked, the noise was deafening, absolutely terrifying and the guns were fired one after the other".
"The musicians just disappeared each time the guns were fired into them". Their bodies were blown to bits, totally destroyed, blood and bits flying everywhere.
"When they brainwash students in North Korea they say: "We can read your words, actions and thoughts, '" Hak said".
There are reports of executions in schoolyards.
Kim Jong Un's depravity and abuses of power have no bounds, extending even to North Korea's upper echelon.
Living in a high-ranking military family, she enjoyed the comforts of a three bedroom home. According to Human Rights Watch, "Ordinary North Korean workers, both men and unmarried women, are required to work at government-assigned enterprises". This week, South Korea reported a recent 12.7 percent decrease in the number of defectors leaving the North to the South between January and August of this year, with 780 fleeing compared to 1,417 throughout 2016.
Hee Yeon also said "the prettiest" schoolgirls were taken away to work in one of Kim's "hundreds of homes around Pyongyang".
"They learn to serve him food like caviar and extremely rare delicacies".
What is more, despite the poverty that the 25 million or so North Koreans live in, Kim apparently hides out in "exquisite bolt-holes" which come with swimming pools, attractive gardens and fountains. "They are also taught how to massage him and they become sex slaves", she said.
The narrated experiences so far is just a little fragment of the insanity of the North Korean leader.
She noted that growing up, she was told that Kim was "like a god", but when she met him, she found him "terrifying, really scary, nothing god-like about him". Hee spoke to the British news outlet in a secret location in Seoul, South Korea days after Kim and his regime conducted its sixth nuclear test this month.
Kim Jong-un has threatened to fire missiles at the island of Guam, where the United States has its foothold in the Pacific Ocean - a key strategic location.
Kim inherited the communist dictatorship, when his father, Kim Jong Ill died in 2011.
But Kim is ratcheting up the prospect of war not from a position of power, but because of his own sense of insecurity, said Hee.
She said: "I have never felt so happy as I felt when I got out".
