The decapitated head of a man was recovered on the gate of a French gas factory Friday, in what authorities suspect was a terrorist act linked to the group ISIS.

One person was declared dead, and 12 injured, in the attack on Air Products, an American-owned company, French media reported.

Two assailants arrived to the factory in Saint-Quentin-Fallavier, in the Southeast of France, with two flags with Arabic lettering on it and drove their car into gas canisters onsite, triggering an explosion. The two terrorists also set off a series of gas bombs, according to reports.

One of the suspected attackers, a 30-year-old man, was taken into custody by law enforcement, according to local reports, adding that the suspect was previously "known to security services."

A man's torso was found at a different part of the facility, according to an official speaking to the AP on condition of anonymity.

French interior minister Bernard Cazeneuve is at the scene of the deadly ambush, and has called for beefed-up security throughout the country. France's President Francois Hollande is en route to the country after a meeting in Brussels.
