Tributes to Victims of Islamist Attack in France

A special Mass in the French town of Trèbes has honoured four people killed by an Islamist gunman on Friday. We hear from a French policeman on the mood in the security forces. Also: the former Catalan leader, Carles Puigdemont, has been detained in Germany; and the jazz ambassadors of the Cold War.
