Further details have emerged about the knife-wielding attacker who killed a man and injured four people in Paris on Saturday night. The suspect - who was shot dead by police on the scene - is understood to be Khamzat Azimov, a French citizen born in Chechnya. It's now being reported that he was on a French watch list of people who were seen as security risks by counter-terrorist police. Correspondent in Paris, Hugh Schofield, talks to Susie Ferguson.
