Further to my earlier post newswires are now reporting that 3 of the suspects holed up in a Saint Denis apartment have been killed
The BBC says:
Three suspects have reportedly been killed, including a woman who blew herself up with a suicide belt. Seven explosions and gunfire were heard.
Two have been arrested. Abdelhamid Abaaoud, the alleged mastermind, is said to be the focus of the operation.
Roads have been blocked off around Rue de la Republique in Saint Denis, in the same district as the Stade de France, where suicide attackers detonated bombs on Friday.
Truckloads of some 50 soldiers joined armed police at the scene.
