Another video captured a tense fire fight between police and terrorists outside the Bataclan.

Award-winning French photographer Patrick Zachmann shot the video on his iPhone, taking cover from behind an unmarked police car as bullets hit the ground nearby.

Sydney Morning Herald Vision outside the Bataclan concert venue is taken by photographer Patrick Zachmann, as he hid behind an unmarked police car.

The footage, which was provided to TIME Magazine, shows police ducking for cover as gunshots ring out.



At one point an officer shields a female civilian as she runs for safety outside the hall.

Zachmann said that he was finishing dinner at a restaurant when he heard police sirens blaring and followed the cars through Paris to the concert hall.

"I heard the shootings from a Kalashnikov," he said. "In the videos, you can actually see the sparks [from the bullets hitting the ground]."



At one point the camera focuses on a police officer who had instructed Zachmann to move to the left in order to use the car's wheels as protection from stray bullets.

"He seemed tensed, very concentrated," Zachmann said.



"I could feel his fear. I could feel that maybe he was not used to this situation. They are trained, but maybe it was the first time he was on [such] a scene. But there was a kind of complicity [between the two of us]. He could have asked me to leave, but he let me [stay] there."

Zachmann said the police officers seemed anxious and nervous and he decided to leave the scene because he felt it was not under control.

"It was panic. You felt that it was not under control, that they didn't know what was going on, from where exactly [the terrorists were] shooting," he said.

The Bataclan attack was one of several across Paris that left 129 people dead and more than 350 injured.

Suicide bombers detonated bombs at the Stade de France football stadium, where France was playing Germany, while gunmen attacked a number of bars and cafes.

Police have issued a wanted notice for one of the alleged assailants from the Bataclan, who is believed to still be on the run.

He was named as Salah Abdeslam, a 26-year-old Belgian-born man.
