"Part of the deck of a bridge under construction collapsed on the Tisseo construction site of line C of the Toulouse metro this Monday," reported La Depech du Midi, a media outlet that covers the region of Midi-Pyrenees. "One person died and two others are in absolute emergency."

Tisseo is the public transport authority for the Toulouse metropolitan area.

The collapsed bridge is located at Labege, about 14 km from the center of Toulouse, the fourth largest city of France. Search operations are still underway to confirm the death toll, the report said.

"According to the first elements available to us, it was some prefabricated elements, the segments on which the deck rests, that have broken.

But it is still too early to know where the failure was," Jean-Michel Lattes, the president of Tisseo, was quoted as saying.
