Saying almost nothing when first arrested, Yassin Salhi, suspected of beheading his boss at a French gas factory, has confessed to his crime, sources close to the investigation said. He will now be transferred to a Paris facility.

The main suspect told detectives he had killed Herve Cornara in a parking area before arriving at the plant in Saint Quentin-Fallavier, before he attempted to cause an explosion.

The suspect’s testimony is currently being verified, but an autopsy has not been able to determine whether it was consistent with the cause of death.

French Prime Minister Manuel Valls has dedicated every available resource in the police and domestic intelligence to the task of combatting Islamic extremism.
