A North Korean defector has revealed she watched as 11 musicians were blown to bits by anti-aircraft guns - and saw her teenage classmates dragged off to become Kim Jong-un's sex slaves.

Hee Yeon Lim, 26, opened up about how the tyrant nonchalantly orders executions of people - including family members.

The Pyongyang graduate risked her life by making the revelations but did so to expose sensitive information about the leader.  She claims he forces the upper classes in Pyongyang to watch the horrific killings and later enjoys £1,000 lunched. She spoke to the Mirror  from a secret location, revealing she knew from an early age 'never to question' the then leader Kim Jong- Il. 

She has changed her name for security reasons and said that she was 'scared' after 'seeing terrible things in Pyongyang'. 

Ms Lim said she was one of 10,000 people who witnessed the killing of 11 musicians after they were accused of making a pornographic film. She added: 'The musicians were brought out, tied up, hooded and apparently gagged, so they could not make a noise, not beg for mercy or even scream.

'What I saw that day made me sick in my stomach. They were lashed to the end of anti-aircraft guns. There were around 10,000 people ordered to watch that day and I was standing 200 feet from these victims.
