A terrorist attack took place on 26 June 2015 in Saint-Quentin-Fallavier, near Lyon, France, when a man, Yassin Salhi (Arabic: يَاسِين صَالِحِيّ), decapitated his employer Hervé Cornara and drove his van into gas cylinders at a gas factory in Saint-Quentin-Fallavier near Lyon, France, which caused an explosion that injured two other people.

French authorities believe that Salhi has links with the Islamist terrorist group the Islamic State of Iraq and Syria (ISIS).

At around 09:30 CEST (07:30 UTC) on 26 June 2015, Yassin Salhi, a delivery driver, gained entrance to the grounds of an Air Products factory in Saint-Quentin-Fallavier near the city of Lyon.

[2][3] He placed Cornara's severed head on a fence railing and planted two Jihadist flag banners alongside it.

Video surveillance footage showed that the perpetrator also tried to open canisters containing flammable chemicals before being subdued minutes later.

At the time of the attack, Salhi was also in regular contact with the French jihadist Sebastian Yunis, known to have left for Syria to join ISIS.

Salhi grew up in Pontarlier, where he was tutored in Arabic by Amar Remimi, treasurer of the Philippe Grenier mosque association.

[3] According to his lawyer, Salhi had been earlier reprimanded by Cornara for dropping equipment from a pallet, and had attacked his former boss for personal reasons.

[18] On 22 December 2015, Salhi committed suicide in Fleury-Mérogis Prison by hanging himself with his bed sheets on the bars of his cell.

[23] The decapitated victim, Hervé Cornara, was the 54-year-old manager of a transport company based in Chassieu, about 20 miles from the attack.

In April 2015 the company won a contract to build, own and operate the world's largest industrial gas complex in Jazan, Saudi Arabia.
