South Korea's president, Moon Jae-in, said on 20 June that North Korea should repatriate South Koreans and Americans detained in the reclusive country. American student Otto Warmbier, arrested for theft of a political notice while visiting North Korea as a tourist, was held prisoner for 17 months. He has died at a Cincinnati hospital just days after being released from captivity - in a coma, his parents said. Doctors caring for him said he had extensive brain damage. Three other United States citizens (ethnic Koreans) and six South Koreans remain in custody. President Moon deplored North Korea’s lack of respect for human rights, and said his government will make every effort to obtain the return of the detainees. US President Donald Trump blamed the ‘brutality of the North Korean regime’ for Mr Warmbier’s death. Several of those detained are Christian missionaries charged with subversion. North Korea defends its ‘sovereign right to ruthlessly punish’ US citizens held for crimes against the state.
