All of Kim Jong Il’s children are said to have lived in Switzerland, as well as the mother of the two youngest sons, who lived in Geneva for some time.[12] First reports said that Kim Jong Un attended the private International School of Berne in Gümligen in Switzerland under the name “Chol-pak” or “Pak-chol” from 1993 to 1998.[13][14] He was described as shy, a good student who got along well with his classmates, and was a basketball fan.[15] He was chaperoned by an older student, thought to be his bodyguard.[16] His elder brother Kim Jong Chul also attended the school with him.

Later, it was reported that Kim Jong Un attended the Liebefeld Steinhölzli state school in Köniz, near Bern, under the name “Pak-un” or “Un-pak” from 1998 until 2000 as the son of an employee of the North Korean embassy in Bern. Authorities confirmed that a North Korean student attended the school during that period. Kim first attended a special class for foreign-language children and later attended the regular classes of the 6th, 7th, 8th and part of the final 9th year, leaving the school abruptly in the autumn of 2000. He was described as a well-integrated and ambitious student who liked to play basketball.
