Man Decapitated In ISIS Terror Attack In France This Morning, Leaving A Severed Head Hanging On A Fence For All To See!! by Geoffrey Grider A man has been decapitated and dozens more injured at a gas product factory in France by terrorists carrying Islamist banners. The attack took place at the headquarters of the American owned Air Products, in Saint-Quentin-Fallavier, near the city of Lyon, in the south east of the country. The murder is believed to have been accompanied by several explosions on the site cause by a terrorist igniting small 'gas bombs' that injured dozens of factory workers. It is believed the explosions may have intended to blow up the entire factory site but failed. The murdered man's head is understood to have been found 30 feet away from his body, hanging on the factory's fence. The dead man's head was covered in Arabic 'inscriptions' before being placed on the fence, according to local journalists at the scene. Murder scene: The murdered man's head is understood to have been found 30 feet away from his body, hanging on the factory's fence. The dead man's head was covered in Arabic 'inscriptions' before being placed on the fence, according to local journalists at the scene A 30-year-old man - named by French Interior Minister Bernard Cazeneuve as Yacine Sali who is understood to have been known to security services since at least 2006 - has already been arrested at the scene, telling police officers that he is a member of the Islamic State terror group. The man is believed not to have a criminal record but was considered to have 'possibly been radicalised'. There remains a great deal of confusion over whether a second terrorist was involved and has now gone on the run, or whether a 'lone wolf' jihadi had actually killed the victim elsewhere and transported his body to site, confusing eyewitnesses. An Islamic flag – possibly that of Islamic State – was found next to the dead body. The man's head was found some 30 feet from the corpse. French journalist Stefan Vries told Sky News: 'There was an explosion at a gas factory. Several people were wounded and there has been one person decapitated on the premises. 'His head was found a couple of yards from his body. A man has been arrested. He was allegedly carrying a flag of the Islamic State. Police fear there may be more attacks.' At a press conference this afternoon, Cazeneuve named the arrested man as Yacine Sali. 'He was investigated in 2006 for radicalisation, but (the probe) was not renewed in 2008. He had no criminal record,' he added. 'This individual has links with the Salafist movement, but had not been identified as having participated in activities of a terrorist nature.' source
