Paris prosecutor Francois Molins says one of the women detained in a police raid over a failed attack near Notre Dame Cathedral was engaged separately to two French extremists who themselves carried out deadly attacks this year.

Molins said the woman was engaged to Larossi Abballa, who killed two police officials in Magnanville in June and filmed the aftermath on Facebook Live before dying in a police raid. 

He said she was also betrothed to Adel Kermiche, who slit the throat of an elderly French priest during morning Mass in July. 

Her current fiance was arrested on Thursday, Molins said.
