French anti-terror prosecutors are investigating an attack at Paris's Orly airport by a gunman who was eventually shot dead by security forces.
Ziyed Ben Belgacem, 39, was killed on Saturday after he put a gun to a soldier's head saying he wanted to "die for Allah", officials say.
Earlier on Saturday, he was involved in a shooting and then a carjacking.
Belgacem is described as having been radicalised in prison, and was on a police watch-list.
His criminal record included convictions for armed robbery and drugs offences, Paris prosecutor Francois Molins told reporters late on Saturday.
Intelligence agents searched his home in Garges-les-Gonesse for evidence of Islamist sympathies, but reportedly found nothing. However, traces of cocaine were discovered during the search.
His father and brother were taken in for questioning in the aftermath of the attack. The brother remains in custody.
Speaking to Europe 1 radio on Sunday, the father said his son was not a terrorist, but someone who never prayed, and drank alcohol and took drugs.
He said he had received a phone call from Belgacem after his initial attack at Garges-les-Gonesse to tell him: "Dad, please forgive me. I've screwed up with a police officer."
The BBC's Hugh Schofield in Paris says the picture is building up of a man on the criminal fringes of society, who also consorted with Islamist radicals.
The attack comes at a sensitive time. France has presidential elections starting next month and remains under a state of emergency.
The sequence of events
Early on Saturday morning, Belgacem was stopped at a checkpoint in Garges-les-Gonesse, north of Paris,.
He fired at police with a pellet gun before escaping in a car that was later found abandoned.
Police say he then stole a car at gunpoint from a woman at Vitry, south of Paris. That car was later found at Orly airport.
Belgacem arrived at the airport and attacked the military patrol in the south terminal.
He tried to seize the servicewoman's automatic weapon, put his gun to her head and said: "I'm here to die for Allah. In any case people are going to die."
He was then shot dead by two other soldiers.
A copy of the Koran was found on his body, Mr Molins added.
Orly - located 13km (8 miles) south of Paris - is the capital's second-largest airport.
Both the west and the south terminals were closed during the security operation. An estimated 3,000 passengers were evacuated.
Flights were suspended for several hours. Both terminals reopened later on Saturday and flight operations gradually resumed.
