Reports from southeastern France say a possible attack and an explosion at a gas factory have killed at least one person.
Witnesses at the factory in Saint-Quentin-Fallavier, southeast of the city of Lyon, say a suspected attacker entered the factory and set off several small explosive devices. A decapitated body was reported found outside the entrance to the factory.
The reports say the attackers bore a flag or banner with Arabic writing on it.
French Interior Minister Bernard Cazeneuve is reported to be en route to the scene.
Details of the attack were sketchy but two French officials said it began mid-morning in the Isere region when the men crashed a car into the entrance of the factory and into gas canisters, touching off the explosion. One attacker was arrested, they said.
Officials spoke on condition of anonymity because they were not authorized to speak to the news media.
France went on high alert after an attack in January that left 20 people dead in the Paris region, including the Islamic extremist attackers.
