French President Emmanuel Macron has admitted that the French state has fuelled home-grown extremism by abandoning its poorest neighbourhoods. He also pledged tough and “sometimes authoritarian” new measures to combat the problem.

As reported by The Associated Press (AP), the president’s pledge is part of a multibillion-euro plan that he outlined on November 14. The focus is to address the suburban housing projects plagued by crime and joblessness.

Macron was unusually harsh in his criticism of previous governments, saying radicalisation took root because the state abdicated its responsibility in impoverished public housing, and extremist preachers filled the void.

He said his government will present about 15 measures to fight radicalisation and will close “unacceptable structures” that promote radicalism and “try to fracture us”.

Several extremist attackers who have targeted France in recent years were raised in troubled French social housing and radicalised here, according to AP.
