Input: The prime minister of France  Manuel Valls   said fighting the appeal of âdeadlyâ doctrines was the greatest challenge the country faced in more than 70 years.  He  said there had to be a âgeneral mobilisationâ of all sectors of society to fight the problem following the terrorist attacks in Paris last year.
âRadicalisation and terrorism are linked. We are faced with a stubborn phenomenon that has widely spread through society and which threatens it because it could expand massively â  Valls  said.
The strategic document that focuses on detection and prevention of radicalisation was unveiled by  Valls  in the presence of several ministers in Franceâs socialist government including those responsible for justice  defence  education  health  culture  youth and sports.

The deradicalisation centres will house young people who âcould have repented and who we will test the sincerity and willingness to be reintegrated back into society for the long termâ   Valls  said.
 He  said the aim of the centres would be to stem the flow of young people to Syria and Iraq and begin the process of deradicalising them.
At least half of the new centres will hold those deemed by a judge to be at risk of radicalisation but cannot be placed in detention   Valls  added.
