Former North Korea spy chief Kim Yong Chol arrives to New York for talks on an upcoming summit between US President Donald Trump and North Korean leader Kim Jong-un. General Kim, 72, is a controversial figure in neighbouring South Korea, and previously served as a negotiator in inter-Korean talks. He is believed to have masterminded numerous attacks on South Korea, including the sinking of the Cheonan military vessel in 2010, which killed 46 sailors.
