Shocking footage taken on the Champs Elysees reveals the moment the first two loud shots can be heard, sending shoppers scattering across the street.
Further shots can be heard being fired in the gun fight after at least one attacker pulled up next to a stationary police van on the busy Paris street before opening fire, killing one officer immediately.
Two further officers and a female tourist were injured in the scuffle, before authorities opened fire – killing the attacker.
The footage shows as the suspect is chased by police
In the video, posted on Twitter, one witness is filming his walk up the Champs Elysees – a popular tourist destination known for its high-class shops.
But then multiple figures can be seen moving around by the side of the police van before the sound of gunfire.
One person falls to the ground in the footage, which is just a couple of seconds long outside, and filmed outside a Marks and Spencer store.

A man got out and opened fire with a kalashnikov on a policeman.
A silver car, believed to have been used by the suspects, can also be seen.
The suspect can then be seen tried to run along the pavement as he continued firing, with the footage capturing the deafening noise as witnesses continue to flee – many screaming in horror as they watch on.

Witness Chelloug, a kitchen assistant, told Reuters: “I came out of the Sephora shop and I was walking along the pavement where an Audi 80 was parked.
“A man got out and opened fire with a kalashnikov on a policeman.
“The policeman fell down. I heard six shots, I was afraid. I have a two year-old girl and I thought I was going to die… He shot straight at the police officer.”
Armed French officers were filmed in the aftermath of the murder, claimed by terror group Islamic State (ISIS), outside a shop in the city.
