Benoît Guyon, a teacher of economic and social sciences at Courbet High School and a union representative for SNES-FSU, said that the right to withdraw was exercised because teachers felt in danger and believed their students were too. According to Guyon, at least a third of the teachers have stopped working due to an increasing feeling of no longer being safe at the high school. An incident occurred around 10:15, which "directly endangered the safety of students and teachers," according to the prefecture of the Territoire-de-Belfort. The school was evacuated calmly, and police responded to the scene. Classes later resumed, and psychological support was put in place to reassure the students, as stated by the prefecture. The rectorate, which oversees the school system, firmly condemned the incident. An investigation was opened by the prosecutor of Belfort, Paul-Edouard Lallois, for "violence in a school establishment." The shot came from inside the high school, from a corridor on the second floor. Investigators favor the hypothesis that the shot came from a student, though the student has not been identified. The mortar, which targeted the entrance hall, exploded behind the students present but "did not hit anyone," according to the magistrate. However, Guyon claimed that students were injured by shrapnel from fireworks. He stated that they realized they were "just two fingers away from a tragedy, with possible serious injuries." Courbet High School, which has about a thousand students, has experienced incidents since the beginning of the students' anger movement. On Friday, a police officer was beaten by teenagers near the school after trying to detain a 17-year-old student he had identified as the perpetrator of projectile throws and trash fires. Five minor suspects were arrested for these violent acts, one of whom was placed under formal investigation and imprisoned, who himself filed a complaint against the police officer. The situation at Courbet High School reflects broader concerns about safety and the impact of student unrest on school environments. Authorities continue to investigate the recent incident, while teachers and students grapple with the emotional and psychological aftermath.
