The nephew of North Korean leader Kim Jong Un, whose family lives in virtual exile, has graduated from an international high school in the southern Bosnian town of Mostar, a school official said on Tuesday. Kim Han Sol, who called his uncle a \"dictator\" in an interview that aired on Finnish TV in 2012, is the son of the North Korean leader\'s half-brother Kim Jong Nam, who fell out of favour with his father Kim Jong-Il following a botched 2001 attempt to enter Japan with a fake passport, reportedly to visit Tokyo Disneyland. \"Kim Han Sol is among 71 student from 28 countries who have obtained a diploma,\" said the official at the Bosnian school, part of the United World Colleges (UWC) network of international schools. \"He left our boarding school on Thursday, a day after diplomas were delivered. We cannot talk about his grades, but he has completed high school with success,\" the official, who asked not to be named, told AFP.
