(Daily Mail) — France’s run-down city suburbs are becoming ‘separate Islamic societies’ cut off from the state, a report has warned.

Arab communities are increasingly rejecting French values and identity to immerse themselves in Muslim culture and lifestyle, it was found.

Muslim pupils often boycott school dinners if the food is not halal and most Arabs oppose marriages to white French citizens, the study by respected political scientist Gilles Kepel revealed.

As a result, France — whose five million Muslims make up Europe’s largest Islamic population — was turning into a ‘divided nation’, the study called Suburbs of the Republic found.

Dr Kepel wrote: ‘In some areas, a third of the population of the town does not hold French nationality, and many residents are drawn to an Islamic identity rather than simply rejecting or failing to find a secular one.

‘French schools, which are rigorously non-religious, have traditionally been seen as having the role of training young citizens of the republic.
