Some French officials are linking the attacks (identical modus operandi, same calibre weapon) - three French soldiers are dead and one in a coma from the earlier attacks. The soldiers were of north African origin, and at least one is reported as Muslim. RIP to all victims of all attacks.

The BBC is reporting that the city is in a lockdown; and if this proves to be a serial killer whose pattern is changing, it must be terrifying as anyone could be next. French police are pouring into the city; I hope there is an arrest soon.
