French police are investigating a fire that broke out in a migrant workers' centre near Paris that left one person dead, several injured and forced the evacuation of 300 people.
Nanterre prosecutors' office said the fire started around 3:30am on Friday in the suburb of Boulogne-Billancourt, west of Paris.
The Paris firefighters' press office said six people were saved "from a certain death" after being rescued with ladders and 13 people suffered minor injuries after inhaling toxic smoke.
Nearly 300 people were evacuated and the fire was quickly extinguished.
Paris police later said one person died.
Paris firefighters said three people were seriously injured when they jumped out of the building's upper windows to escape the flames.
It was unclear whether the person who died was among those three.
Prime Minister Bernard Cazeneuve promised to investigate and expressed his "solidarity" with the victims in a message posted on Twitter.

Investigators have yet to determine whether the fire was arson.
