An explosion at a train station in North Korea killed around 170 people and destroyed thousands of homes in April 2004. In a rare moment of openness, authorities in Pyongyang asked the United Nations for help. Hear from a Western aid worker who travelled to Ryongchon to assess the damage.

Also on the programme: the 1940s legal challenge to the segregation of Mexican Americans in the US; Easter for Christians in 1980s Moscow; the push by Polish union Solidarity for legal recognition; plus the unfolding drama of the Bay of Pigs invasion of Cuba.
