A man armed with a knife stabbed a teacher to death at the high school in northern France he once attended and critically wounded another teacher and a security guard Friday.
According to BBC, the attack happened at Gambetta High School in the northern city of Arras at about 11:00 local time, 09:00 GMT.
The authorities in France said the attack was being investigated as potential terrorism amid soaring global tensions over the war between Israel and Hamas.
French anti-terror prosecutors said they were leading the investigation into the attack at the Gambetta high school in the city of Arras, some 115 miles north of Paris. They said they were investigating charges including terror-related murder and attempted murder against the suspect, who was arrested.
National police said the suspected assailant was a Russian national of Chechen origin. The French intelligence services said the suspect had been closely watched since the summer with tails and telephone surveillance and was stopped as recently as Thursday for a police check that found no wrongdoing.
A police officer, Sliman Hamzi, who was one of the first on the scene said the suspected attacker, a former student at the school, shouted “Allahu akbar,” or “God is great” in Arabic.
Hamzi said he was alerted by another officer who was passing in front of the high school and called in. He “was shouting ‘someone is attacking with a knife,’” Hamzi said
Hamzi said he rushed to the school and saw a male victim lying on the ground outside the school and the attacker being taken away.
“Colleagues arrived quickly but unfortunately couldn’t save the victim,” Hamzi said.
Police said two other men, a second teacher and a security guard, were in critical condition.
School attacks are rare in France. President Emmanuel Macron was heading to the scene along with the interior and education ministers, and the government asked authorities to heighten vigilance at all schools across the country.
