Revealing Kim Jong-un's secret life in Switzerland

Former teachers of North Korean leader Kim Jong-un have shared extraordinary stories about the secret life and study of the student from Pyongyang in Switzerland.

Daily Mail reported that leader Kim Jong-un and his brother Kim Jong Chul and sister Kim Yo Jong attended Liebefeld-Steinhoelzli public school in the town of Koeniz, south of the capital Bern, Switzerland.

According to a former teacher at the school, Kim Jong Un enjoys playing basketball, speaks German with a Bern accent and enjoys singing the Swiss classic 'Alperose'.

Although no one knows exactly when Kim Jong Un arrived in Bern, the North Korean leader is believed to have arrived in Switzerland in 1991 when he was just 7 years old.

Officials at Koeniz admitted that Kim Jong-un attended the Liebefeld-Steinhoelzli school from August 1998 to the fall of 2000 under the alias "Pak Un".

"He registered as the son of a North Korean embassy employee," a city official said.

Kim Jong-un studied in a class for foreign students and after a year, he was transferred to regular classes.

Teachers at the school described him as a maths student who enjoyed learning German, was sociable, diligent and ambitious. While former classmates remember Kim Jong-un as a basketball enthusiast who was a particular fan of the National Basketball Association (NBA) and Chicago Bulls star Michael Jordan.

Kim Jong-un's advisor during his stay in Switzerland was Ri Su Yong (77 years old), former North Korean Ambassador to Switzerland. He arranged Kim Jong-un's life very carefully, including security and accommodation in an apartment in the center of Koeniz town.

After 22 years as ambassador to Switzerland, Ri Su Yong became North Korea's foreign minister until 2016.

He still holds an important position in the North Korean Politburo and is considered by experts to be one of the people close to the young leader. Swiss media even described him as "Kim Jong-un's Swiss adoptive father".
