The explosion left the road covered with debris and destroyed the facades of adjacent buildings. The window shutters were torn from their hinges and the windows shattered, covering the glass area. The vehicles have been crushed and at least one has been turned upside down by the power of the explosion.
According to the videos and photographs of the scene, the crews were busy evacuating people from the upper levels of buildings along the road in the aftermath of the explosion.  French interior minister Christophe Castaner visited the scene less than two hours after the explosion and said more than 200 firefighters were involved in the rescue operation.
"My first thoughts are with the victims and their families," he said in a tweet .
Staff and guests of Hotel Pax Opéra a few blocks down the street heard the explosion, according to Francesca Perna, receptionist.
"The police arrive immediately to see what happened," he told NBC News.
The hotel was not damaged, Perna confirmed, adding: "The guests asked me what happened but here in our hotel there is no problem, the situation is quiet".
