A French prosecutor confirmed Tuesday that the man who beheaded his boss and tried to blow up a gas factory in Lyon had a "terrorist motive" and links to the Takfiri group, ISIL (so-called Islamic State in Iraq and Levant) in Syria.

The investigation "indicates a terrorist motive in Yassin Salhi's act, even though it is justified by personal considerations," said Paris chief prosecutor Francois Molins.

The 35-year-old, long known to security services for his radical views, was arrested Friday after an attack in which he rammed his gas-filled delivery van into a warehouse containing dangerous chemicals, causing an explosion.

Firefighters alerted by the blast found him trying to open gas bottles inside the Air Products factory, before making the grisly discovery of the severed head of Salhi's 54-year-old boss Herve Cornara.

"Salhi decapitated his victim, he hung the head on a fence to get maximum publicity, as he told us during interrogation," said Molins.
The prosecutor said that Salhi claimed to have strangled his boss "with one hand" before stopping 500 metres before the factory to decapitate him with a knife with a 25 cm blade.

The head was attached to the fence with a chain and surrounded by two
Extremist flags which Salhi said he had bought the night before the attack.
"This corresponds very precisely to the orders of Daesh which calls regularly for acts of terrorism on French soil and in particular to cut the throats of unbelievers,” he said referring to ISIL in Arabic.

"The decapitation recalls the habitual modus operandi of this terrorist organization," said Molins.

Salhi, who refused to talk for his first 24 hours in custody, later gave scattered testimony, claiming he was suffering from amnesia and had no memory of the macabre staging of the severed head.

He also claimed he didn't recall sending two photos of the crime to a French extremist in Syria, including a selfie with the head, and a picture of the body draped in the extremist flags with the head posed on the torso.

The suspect claimed his motives were "purely personal and his act was not terrorist," said Molins, adding that Salhi had blamed a fight with his employer as well as a dispute with his wife for pushing him to commit the crime.

But Salhi was in "regular contact" with the French Takfiri Sebastian Yunis, 30, known to have left for Syria last November.

During a raid on those close to Yunis, who is from Besancon in eastern France, police uncovered a telephone used to contact him in which he said in a Whatsapp conversation on the day of the attack that he indeed knew Yassin and was "one of the reasons he did that", referring to the crime.

Yunis said in the message he had asked permission from ISIL to publish the gruesome photos.

Molins said Salhi had spent a year in Syria in 2009 with his wife and children, claiming he was there to learn Arabic.
