Three people have been injured following an explosion at a university in Lyon.
The explosion occurred at the Mendel building at the La Doua campus of the university.
Police and university sources said that work had been ongoing on the building's roof and that a gas bottle exploded, starting the blaze.
The building has been evacuated however other parts of the campus remain open.
Video footage from the scene showed the sheer size of the fire with thick black smoke billowing into the sky.
The University of Leon said that the situation was under control however fire crews will continue working throughout the day to secure the premises.
The explosion comes days after a blast apparently caused by a gas leak hit a Paris bakery, killing four people and injuring several.
