The French authorities have launched inspections of dozens of mosques and prayer halls suspected of links to Islamist extremism.
Interior Minister Gérald Darmanin announced the crackdown, saying some could be closed if found to be encouraging «separatism».
It comes a week before the unveiling of a new law to combat such extremism. It is a response to attacks in October, blamed on Islamists, including the beheading of teacher Samuel Paty.
