Teacher stabbed to death and two more injured in school knife attack in France

French Interior Minister Gerald Darmanin confirmed the attack on social media.

"A police operation took place at the Gambetta high school in Arras," he said.

"The perpetrator was arrested by the police."

The suspect is around 20 years old and could have been a former pupil.

His brother was reportedly also arrested.

The attack unfolded in the northern city at around 11am local time (10am GMT).

French police announced the situation was under control just before midday.

The Elysee Palace has confirmed French President Emmanuel Macron will travel to the scene of the stabbing.

French news outlets BFMTV and Le Parisien have claimed that the suspect shouted "Allahu Akhbar" during the incident.

French anti-terror prosecutors have taken over the investigation.

However, nothing so far has pointed to a potential link between the attack and the current situation in Israel.

One pupil told outlet La Voix du Nord: "We were leaving class to go to the canteen when we saw the guy with two knives attacking the teacher, who had blood on him.

"He tried to calm him down and protect us. He told us to leave, but we didn’t really understand, so we ran and others went back upstairs."

A video circulating on social media shows the armed attacker approaching people in the school car park.

The victims attempted to protect themselves using a chair.

However, one person falls to the floor and is then beaten by the perpetrator.
