French attacks - 'each one is different'
French Socialist MP Christophe Premat talks of security failings and the need for unity after two men murdered a priest during a Roman Catholic Mass in a suburb of Rouen.
One of the attackers was well known to security services and was wearing a surveillance tag at the time of the attack.
As well as the murder of 84-year-old Father Jacques Hamel, another of the four people taken hostage is being treated in hospital.
