A violent gas explosion has occurred in the eastern French city of Dijon. Several people have been reported injured, and at least one person trapped under rubble.
The blast occurred Friday morning with early reports saying nine people were injured.
The impact of the blast was so enormous that a four-storey building collapsed.
Fire, police and ambulance crews rushed to the scene of the explosion in the centre of Dijon.
Plumes of thick white smoke billowed from the surrounding houses in the city.
Local councillor Laurent Bourguignat said paramedics and rescue teams were at the scene shortly after 9am.
Reports said the local attorney had ruled out terrorism, saying the explosion was the result of an accident or a suicide attempt.
