A French teacher, who had shown students cartoons of the Prophet Mohammed, was beheaded outside his school in Conflans Sainte-Honorine, on the outskirts of Paris, on Friday. The assailant, whose identity is yet to be ascertained, was shot by police as they tried to arrest him and later died of his injuries. France has witnessed a wave of Islamist violence since the 2015 terror attacks on the satirical magazine Charlie Hebdo and a Jewish supermarket in the capital.
