A policewoman shot in an attack in South Paris has now died and the gunman remains on the run.
No link has yet been established with the previous day's deadly attack on a satirical magazine.
The gunman was on the run, said Interior Minister Bernard Cazeneuve - who rushed to the scene at Malakoff just south of the city - contradicting information given earlier by a source close to the case, who said the suspect had been detained.
Police initially said the two victims were critical, but Cazeneuve said just the policewoman was fighting for her life.
