Inside Europe: Czechs mark 50 anniversary of Palach's death

Fifty years ago, 20-year-old Czech student Jan Palach poured flammable liquid over himself and lit a match in Prague's Wenceslas Square. He was protesting not just at the Soviet-led invasion of Czechoslovakia five months previously, but at what he saw as public apathy towards it. His funeral became a major protest against the occupation. Rob Cameron reports on how Czechs are remembering him.
