Heavy gunfire broke out on Wednesday as French police launched a raid in a Paris suburb, a media report said.
Police told Saint-Denis residents to clear the vicinity of the operation that started at 4.30 a.m. on Wednesday, Aljazeera reported.
The shots ceased after 15 minutes and then resumed at 5 a.m.
It was not clear whether the raid was related to the investigation into Friday's deadly attacks in Paris that claimed at least 129 lives and injured over 350 people.
