Heavy shooting has been heard in the northern Paris suburb of Saint Denis and reports say a police operation linked to last Friday’s attacks is under way there.

Some police have been wounded, French TV station BFMTV reported.

Earlier, security sources said surveillance video showed a possible ninth assailant during Friday’s attacks in which 129 people died.

The so-called Islamic State (IS) group has said it carried out the attacks.

One report said roads had been blocked off around Place Jean Jaures in Saint Denis, in the same district as the Stade de France, where suicide attackers detonated bombs on Friday.
