The man who stabbed to death a police employee at a police station outside Paris on Friday shouted "Allahu Akbar" (God is Greatest) during the attack, a source close to the inquiry told AFP. France's anti-terrorism prosecutor Jean-Francois Ricard, whose office is leading the investigation, said outside the station in Rambouillet that "comments made by the assailant" indicated a terror motive by the Tunisian suspect, who was shot and killed by police. sm-js/adp/jv
