Three consecutive explosions rocked an industrial zone near the southwestern French city of Bordeaux early Sunday, local media reported.
There were no immediate reports of casualties and damage.
The blasts, along with strong fire, broke out at around 6:40 local time (0440 GMT) in a company specializing in chemical products transportation at the industrial zone in Bassens, near Bordeaux, French radio France Bleu Gironde reported on its Twitter.
Firefighters had already been on the scene to conduct rescue operations.
"The situation seems under control," Mayor of Bassens Jean-Pierre Turon told news channel iTele, adding that two firefighters were slight injured in the rescue operations.
The outbreak of a fire may have caused the explosion of two or three tankers filled with gas, he said.
