French police interrogate attack suspect after grisly decapitation

French police interrogated a suspected Islamist Saturday as they tried to piece together an attack in which the man put his boss’s severed head on display. A suspect, Yassin Salhi, 35, was arrested after causing an explosion by driving a delivery van into a warehouse containing bottles of dangerous gas and chemicals at the US-owned Air Products. The prosecutor in the case said Salhi was overpowered by firefighters as he was trying to open acetone bottles in what is believed to have been an attempt to cause a larger explosion.

It’s difficult for a society to live for years under the threat of attack. The question is not… if there will be another attack, but when.

The prosecutor said Salhi’s wife, sister and another man had also been taken into custody. The second man is being investigated on terrorism-related charges but his link to the attack is not clear, and Molins said there was no indication that Salhi had an accomplice with him. For months, Europe has been on high alert for so-called “lone wolf” attacks by supporters of Islamic State, which has urged its followers to strike wherever they can.
