Kim Jong-un's sister becomes 1st in family to visit S Korea
North Korean leader Kim Jong-un's younger sister, Kim Yo-jong, will become the first member of the Kim dynasty to visit South Korea when she attends the opening ceremony of the 2018 Winter Olympics there on Friday. Jong-un had promoted his sister, who is blacklisted by the US over "severe human rights abuses", to North Korea's top decision-making body last year.
