TOULON, France -- Authorities said Thursday at least 13 people died when a building in the Mediterranean city of Toulon collapsed in a suspected gas explosion.
Rescue workers pulled out a 13th body after working through the night following the explosion Wednesday in Toulon, about 450 miles southeast of Paris, police said.
Thirty six people were injured in the blast.
The dead included two children aged 5 and 12.
Police said the most likely cause of the explosion was a gas leak, possibly in a dental laboratory in the building.
Three hundred firemen, soldiers, civil protection and ambulance workers were dispatched after the blast destroyed the 18th Century building and severely damaged several others surrounding it.
'I heard an enormous noise and then everything went black. Rocks began to fall everywhere,' said Reine-May Picard, an apprentice baker who was walking near the building at the time of the blast.
