He might only be 30 years old but baby-faced North Korean leader Kim Jong-un claims to be on the verge of taking his country to war.

The rogue state last night said it was in a "state of war" with its neighbours to the South - and threatened to "dissolve" the United States.

Here are the top snippets revealed about Kim Jong-un…

1) He is a Daejang in the Korean People's Army, a military rank equivalent to that of a General.

2) Kim is said to have studied computer science privately in North Korea, obtaining two degrees - one in physics at Kim Il Sung University and another at the Kim Il Sung Military Academy.

3) Reports have also suggested that he is a diabetic and suffers from hypertension.

4) Named vice chairman of the Central Military Commission on 28 September 2010, Kim was also appointed to the Central Committee of the Workers' Party, in an apparent nod to becoming his father’s successor.

5) During his time at the Liebefeld-Steinholzi school, staff had not idea who his father was – being continually fobbed off with various excuses by the teenage pupil’s shadowy chaperones about why his parents could not attend end of term meetings.

6) Going under the name of ‘Pak Un’, Swiss authorities were told that Kim was the son of an employee at North Korea’s embassy when he enrolled in August 1998.

7) ‘Pak’ arrived in Europe with a “fantastic” collection of Nike trainers worth thousands of pounds. Each pair of his trainers was worth more than four times the average monthly salary in North Korea.

8) Amazingly, ‘Pak’ only revealed his identity to his closest school friend, Portuguese teenager Joao Micaelo.

9) He lived in a large flat at No 10 Kirchstrasse, a sedate suburban street with two pizza cafes, a bank and a Co-op supermarket.

10) Friends say he was “obsessed” with basketball and showed “absolutely no interest” in politics.

11) Noted as the “fiercely competitive” star of his school basketball team, one of his heroes was LA Lakers ace Kobe Bryant

12) One friend, Marco Imhof, remembers seeing two North Korean women videotaping Jong-un when he played basketball. Imhof said: “I thought it strange, but put it down to being a Korean thing. He hated to lose. Winning was very important.”

13) After enrolling at the posh Swiss school, Jong-un had to attend a special language course for students with poor German. He went on to speak it fluently, along with basic English and French.

14) He once got in trouble when a teacher, checking pupils’ bags for cheat notes before an exam, caught him with a bondage porn mag.

15) His favourite film star during his time at school was kung fu king Jackie Chan and he spent hours watching his action movies.

16) His former sushi chef has claimed Jong-Un was favoured for succession by his father over his brother Kim Jong-chul on the basis that Jong-chul is ‘too while Jong-un is "exactly like his father".
