An explosion at a Paris apartment has left at least three dead, Paralel.Az reports citing French press.

The cause of the explosion is not yet known. Several police and emergency services vehicles were seen outside of an apartment building in the 11th arrondissement on the eastern side of the city.

“The neighbors do not understand what could have triggered this explosion, because there is no gas in the building,”the deputy mayor of the 11th arrondissement, Luc Lebon said.
