PARIS—A U.S.-owned industrial gas factory in southeastern France was targeted in a suspected terror attack on Friday morning, French authorities said, noting the decapitated remains of one victim were found at the site of the assault.
Authorities found a decapitated body along with an inscription, French President François Hollande told a news conference in Brussels. Two police officers said a severed head was also found at the site. The officers said the inscription was in Arabic.
The Interior Ministry said Yassine Salhi, 35, who had previously been under surveillance by French intelligence services and is believed to have links to an ultrafundamentalist strain of Islam, had been detained in connection with the attack.
Witnesses said they heard an explosion around 10 a.m. on Friday. Mr. Hollande said a vehicle drove into the plant with an intent to “provoke an explosion.” The president said the driver of the car might have been accompanied by someone else.
