Three dead and many injured after Paris gas explosion.

Two firefighters and a Spanish woman have died due to a gas leak causing an explosion in a six-floor building, on Rue de Trevise in the 9th arrondissement in Paris, this morning.

10 people are seriously injured and 37 more have been harmed by the explosion.

Police authorities are still investigating the origins of the explosion, but so far reports have said that the origins of the explosion came from an accidental leak of a 'pocket of gas'.

The explosion was so big that windows were smashed, cars were overturned and it was felt several streets away.
