VIDEO: French train gunman 'dumbfounded' by terrorist tag
As details emerged of the gunman’s early adult life in Spain, lawyer Sophie David said her client - now in detention near Paris - also looked ill and malnourished.
French and Spanish sources close to the case have identified him as a 26-year-old Moroccan named Ayoub el Khazzani who was known to European authorities as a suspected Islamist militant.
French Interior Minister Bernard Cazeneuve said on Saturday there had been "several shots" before the Moroccan was subdued by the passengers, who included three Americans.
