A report released Saturday by a specialized NGO alleges widespread and severe abuse at Notre-Dame-De-Bétharram, a boarding school in southwestern France, and other institutions run by the same religious congregation. The abuse, described as involving “exceptional gravity” violence, including acts likened to “torture” and “sadism,” allegedly occurred between 1950 and the late 1990s. Projections suggest between 700 and 1,500 students may have been victims. The report details claims of mass crimes committed against pupils. Authorities have not yet commented on the findings, but the allegations are prompting calls for a thorough investigation. The school, located near Lourdes, is now facing intense scrutiny as details emerge regarding the alleged systematic abuse.
