There were no immediate reports of any smoke or fire.
Paris police said on Twitter that it was a fighter jet that had broke the sound barrier.
Un bruit très important à été entendu à Paris et en région parisienne. Il n’y a pas d’explosion, il s’agit d’un avion de chasse qui a franchi le mur du son.
N’encombrez pas les lignes de secours !
