Teacher beheaded in Paris street, nine held

French police have arrested nine people after a suspected Islamist sympathiser beheaded a school teacher on the street of a Paris suburb on Friday, police sources said, reports Reuters.

Investigators were trying to establish whether the attacker, who was shot dead by police, had acted alone or had accomplices. French media reported that he was an 18-year-old of Chechen origin.

Witnesses heard the assailant shout "Allahu Akbar" or "God is Greatest", a police source said. His victim, a history teacher, had earlier this month shown his pupils cartoons of the Prophet Mohammad in a civics class on freedom of expression.

President Emmanuel Macron called the incident Islamist terrorism.

Four relatives of the attacker, including a minor, were detained in the immediate hours after the attack in the middle-class suburb of Conflans-Sainte-Honorine, the police sources said.

Five more were detained overnight, among them two parents of pupils at the College du Bois d'Aulne where the teacher was employed.
