France is deploying 7,000 troops after a deadly school stabbing by a suspected Islamic radical

ARRAS, France (AP) — France will mobilize up to 7,000 soldiers to increase security around the country after a teacher was fatally stabbed and three other people wounded in a school attack by a former student suspected of Islamic radicalization, the president’s office said Saturday.

Some children and personnel returned to the Gambetta-Carnot school in the northern city of Arras as it reopened Saturday morning, after a schoolday attack Friday that rattled France in a context of global tensions over the Israel-Hamas war.

Counterterrorism authorities are investigating the stabbing, and the suspected assailant and several others are in custody, prosecutors said. The suspect is a Chechen who had attended the school and had been under recent surveillance by intelligence services for radicalization.

The government heightened the national threat alert, and President Emmanuel Macron ordered up to 7,000 soldiers deployed by Monday night and until further notice to bolster security and vigilance around France, his office said. The “Attack Emergency” threat posture allows the government to temporarily mobilize the military to protect public places among other measures.
