France on High Alert After Decapitated Body Found

France has raised its security alert to the highest level after police discovered a decapitated body and flags with Arabic inscriptions following an attack in which a man seemingly tried to blow up a factory belonging to a US gas company. A suspect arrested at the scene at Saint-Quentin-Fallavier, near Lyon in south-west France, was named by the French prosecutor as 35-year-old Yassin Salhi, an employee at a transport company run by the victim.
