Images shared on social media show a major emergency deployment to fight the fire in rue de Longchamp, behind the Trocadero, in the 16th borough of the French capital. According to local media, the fire broke out on the first floor of the building before spreading through the facade to the rest of the building.
Firefighters were called to the scene around 9 a.m., with more than 100 working on the incident, the Paris Fire Brigade (BSPP) said.
According to the BSPP, 13 people were injured, two of them in critical condition.
The service wrote on Twitter: “Avoid the area and do not unnecessarily clog emergency lines. Residents, be careful.”
Eyewitness Sara Tuckey told Express.co.uk: “People are visibly shaken, some being evacuated in their pajamas.
“The gated area is important and they are doing their best to control the crowds.”
Some people were rescued from their homes through windows, the BSPP said, while nearby residents were evacuated.
The source of the fire is still unclear.
The fire follows the tragic death of a person after a major fire broke out on Tuesday morning in the 11th of Paris borough.
Called around 12:40 a.m., the firefighters deployed two hoses and 45 firefighters to control the flames in a 70m² apartment which quickly spread to the roof of the building.
The building was completely destroyed, while much of the roof and facade were also badly damaged.
