In the battle for the hearts and minds of French Muslims, confronting radicalisation is among the biggest and most sensitive issues facing government and community leaders.
A 60-point plan unveiled by President Emmanuel Macron's prime minister Edouard Philippe targets prisons, schools and the treatment of fighters – and their children – returning from Syria, Iraq and other conflict zones.
The blueprint for confronting what Mr Philippe called the "threat to our society" posed by extremism imposes unprecedented responsibility on employers, schools and sports clubs to root out radicalised employees, teachers, pupils and members. But he also admitted the government cannot confound the problem alone, and needs to create a common culture of vigilance.
Reinforcing existing measures allowing the dismissal of civil servants or members of the armed forces who arouse suspicion, Mr Macron has ordered officials to identify by the end of June how to spot radicalisation among all public sector workers.
