Security has been stepped up at Notre Dame after the discovery of the suspect vehicle
Three women arrested over a foiled attack in Paris were directed by so-called Islamic State (IS) from Syria, a French prosecutor has said.
The group "wanted to make the women into fighters", Paris prosecutor Francois Molins said.
A policeman was stabbed during an operation late on Thursday to arrest the women, after the discovery of a suspect car containing gas canisters.
