Paris (CNN) Two people were killed and several were injured after a bridge collapsed Monday in southwest France, according to local authorities.

A 15-year-old girl died after the bridge leading to the small town of Mirepoix-sur-Tarn collapsed at 8 a.m. local time, Toulouse prosecutor Dominique Alzeari said. The girl's mother was rescued by witnesses at the scene. Three vehicles were caught in the bridge collapse, according to the prosecutor.

The body of a truck driver was found after a search involving more than 60 rescue workers, the mayor of Mirepoix-sur-Tarn, Eric Oget, and rescue workers told AFP.

"The body, which is in the truck, has not yet been freed," Oget added.

The bridge collapsed when suspension cables snapped, crashing the structure into the Tarn river, AFP reported. The environment ministry told AFP that recent bridge inspections had "shown no security defects."
