The Fifth Floor visits the BBC's Seoul Bureau to meet the journalists working for BBC Korean, serving audiences across the whole of the Korean peninsula, with different output for both North and South Korea. Journalists David Oh, Hyunjung Kim and Yuna Ku talk about the stories they've been working on for the domestic audience, from the growing global interest in Korean popular culture to what divides, and unites, Koreans. They also broadcast a daily radio programme to North Korea. Editor Woongbee Lee and journalist Rachel Lee explain how they keep this largely unknown audience informed about worldwide news, as well as stories about their own country unreported by their state broadcasters. And on the first anniversary of the Itaewon Halloween tragedy in which 159 people became trapped in huge crowds and died, unable to breathe, we hear from Jungmin Choi who filmed on the scene in the days after the disaster, and Yuna Ku, who is working on stories to mark the anniversary, about the victims' families' fight for justice.
