Three Injured in Huge Blast at Lyon University Campus
TEHRAN (Tasnim) - Three people have been injured in a massive explosion at a university building in Lyon, France.
Footage of the blast shows a fireball erupting into the sky above the building where a large fire could already be seen on the roof.
The building on the La Doua campus in Villeurbanne, north of Lyon city centre, is a science library.
The area has been evacuated and firefighters are on the scene.
Police told Reuters works were being carried out on the roof and the fire began after a gas bottle exploded.
The university told AP construction work was the cause and the explosion was “accidental”.
The university said multiple explosions occurred and had been "caused by renovation work."
Images posted on social networks showed massive plumes of black smoke and flickering flames rising above the campus in the Lyon suburb of Villeurbanne.
Many captured the moment of the largest blast which sent a mushroom cloud metres into the air above the science building.
Authorities in the city and university insisted there were no risks of chemical leaks.
The incident comes days after a blast apparently caused by a gas leak hit a Paris bakery, killing four people.
In that explosion a gas leak had been reported immediately before the blast in which dozens were injured and twelve neighbouring buildings were damaged.
