Attack On French Gas Factory Is Being Investigated As An Act Of Terrorism

According to officials, a suspected terror attack on a French gas factory has left at least one person dead and several injured Friday. French media has reported a decapitated head along with an Islamist flag were found at the site, though that has been unconfirmed by officials, according to CNN. The attack on an Air Products factory in southeastern France near Grenoble could be the second terrorism act on French soil this year, following the horrific shooting spree in Paris from satirical magazine Charlie Hebdo's office to a Jewish market that left 17 dead in January. Update: President Francois Hollande confirmed Friday one person died and two others were injured in the "pure terrorist attack." Hollande said a severed head was found at the scene.

The Associated Press reported that two attackers arrived at the factory by car with banners in Arabic. The car crashed into the entrance and set off an explosion by driving into gas canisters. Reuters reported that one suspect was in police custody. The status of the other attacker is unknown.

France has been on heightened security alert since the Charlie Hebdo attack. In April, Prime Minister Manuel Valls told reporters French security thwarted at least five terrorism attacks since January. "The threat has never been so serious, we have never had to face this kind of terrorism in all our history," he said. The French government has opened a terrorism investigation into the factory attack.
