French cops probe suspect after decapitation

French police interrogated a suspected Islamist on Satyrday as they tried to piece together an attack in which the man put his boss’s severed head on display in the second jihadist attack to hit France in six months.

PM Manuel Valls, who cut short an official trip to South America to return home, warned that France faced more attacks and that assault on a gas factory near the second city of Lyon would increase tensions in the country and put citizens’ resilience “to the test”.
