A 48-year-old female police employee was fatally stabbed in Rambouillet, France, and authorities are treating it as a possible terror attack.

The woman, whose identity has not yet been released, was stabbed in the neck around 2:20 p.m., as she was returning from her lunch break, the BBC reported. Rambouillet is a town located southwest of Paris.

A security official told Reuters the attacker was of Tunisian nationality and living in France legally. The BBC reported that the attacker was 36 years old, and was shot and later died in the hospital.

A motive remains unknown, but French President Emmanuel Macron said the stabbing was a terror attack.

"We will stop at nothing in our resolute fight against Islamist terrorism," Macron tweeted.

A source close to the investigation told Reuters the attacker had shouted "Allahu Akbar" - or "God is Greatest" - during the attack.

French anti-terrorism prosecutors have taken over the investigation, and are treating the stabbing as a possible terror attack.

Prime Minister Jean Castex said in a tweet: "The Republic has just lost one of its everyday heroes in a barbaric gesture of infinite cowardice."
