A fire broke out on the roof of a building in Paris' 13th arrondissement near Porte d'Ivry, causing two gas cylinders to explode, local media outlets said on Tuesday.
The six-story building was under construction, and all residents were evacuated as a precaution when the incident took place, according to Le Parisien.
One worker was injured, and a firefighter suffered moderate injuries while responding to the blaze.
Three additional gas cylinders remain on the roof, creating a continued risk of further explosions.
Authorities have set up a security perimeter, and local residents are waiting to return to their homes.
