Excerpt:
Paris City Hall on Wednesday decided to launch a lawsuit over reports by US news channel Fox News that there were "no-go zones" in the French capital that police and non-Muslims avoid.
In the wake of last month's attacks on Paris, Fox News aired reports, later widely derided, that suggested parts of the French capital and Britain's second city of Birmingham were run under Islamic Sharia law.
The City Hall will launch a suit "against persons unknown" for defamation.
