At least four people died Sunday following an explosion and collapse of a four-story building in a northeastern Paris suburb, Reuters reported.
The deaths included an 8-year-old child and an 80-year-old woman who died as emergency workers carried her out of the rubble.
A woman in her forties and her child were found dead later in the afternoon. Four adults are still missing.
Eleven people were injured in the incident.
About 150 emergency workers were on scene searching for missing people, some working with dogs to locate the missing, according to the Associated Press.
Speaking to reporters on the scene in Rosny-Sous-Bois, Reuters reports Interior Minister Bernard Cazeneuve said the explosion appeared to have been caused by a gas leak.
