The Nanterre prosecutors’ office said the fire started at around 3:30am in the suburb of Boulogne-Billancourt, west of Paris.




Investigators said they suspected the fire may be of criminal origin, adding that they had found traces of combustible material and a fire accelerant at the building’s entrance.


Two people were seriously injured when they jumped out of the building’s upper windows to escape the flames.


One of them, identified as a 40-year-old Malian, was rushed unconscious to a nearby hospital, where he was later pronounced dead.
