Australia said it was"urgently seeking clarification" Thursday on the fate of a 29-year-old tour guide and student feared detained in North Korea.
His friend Crispin Rovere described him as"the nicest guy on Earth" and said that he was"only ever interested in sharing North Korea's culture with the world and improving people-to-people connections." Trump -- who will go on to South Korea amid rumours of renewed talks with the North -- had been intimately involved in the case of Otto Warmbier, a University of Virginia student who was imprisoned during a tour of the authoritarian state after being accused of taking down a propaganda poster.
Canberra advises against non-essential travel to North Korea -- recommending Australians"stay as short a time as possible, eliminate unnecessary activities, and review your security arrangements".The vast majority of foreign students in North Korea come from neighbouring China, where education is significantly more expensive.
In a post in January this year, Sigley described a strong interest in east Asia and"socialism" and recounted his first trip to North Korea in 2012.
