France will create centres in each region of the country to de-radicalise people or prevent them becoming becoming involved in jihadist groups, Prime Minister Manuel Valls said Monday as he laid out new anti-terror measures.

The plan, which will cost an additional 40 million euros ($45.5 million) by 2018 on top of the current funding, aims to double existing efforts to try to help people already in jihadist networks or those likely to join such groups.
