At least 13 people have died following a fire at a birthday party in the French city of Rouen.
The blaze swept through the basement of a bar called Cuba Libre where the party was being held last night.
Six people were rescued from the fire and are receiving treatment for their injuries.
According to authorities, the victims were all aged from 18 to 25.
More than 50 firefighters battled the city centre blaze last night.
Local media reported the fire brigade had the incident under control after around half an hour.
A fire began after candles were lit on a birthday cake, website Paris-Normandie reported.
The victims were reportedly killed by toxic gas as polystyrene in the ceiling caught light.
French interior minister Bernard Cazeneuve said at least 13 were dead and six others injured.
Prime Minister Manuel Valls tweeted: “Deep sadness with regard to the tragedy which mowed down 13 young lives.
“Compassion and support for the afflicted families."
The bodies were taken to a nearby hospital but are yet to be identified.
Mayor of Rouen, Yvon Robert, described the fire as “the greatest catastrophe” for his city.
A judicial inquiry is now underway to determine the cause of the blaze.
