ARRAS, France—A man of Chechen origin who was under surveillance by the French security services over suspected radicalization stabbed a teacher to death at his former high school and critically wounded two other people in northern France on Friday, authorities said.
The attack was being investigated as potential terrorism amid soaring global tensions over the war between Israel and Hamas. It also happened almost three years after another teacher, Samuel Paty. was beheaded by a radicalized Chechen near a Paris area school.
