Protesters hold placards including one reading "Bismillah it's the darkness" during a blockade of HEC (Hautes Etudes Commerciales) business school in Jouy-en-Josas, southwest of Paris, on October 15, 2026 as part of a nationwide protest movement over learning conditions. Since late September, pupils have barred the entrances to hundreds of schools, complaining of teacher absences, overloaded timetables, dilapidated classrooms and buildings ill-adapted to rising temperatures, among other grievances.
