New video has emerged of the Paris gunmen on the streets of the city after carrying out their attack on Charlie Hebdo magazine last week, reports Sky News.
The footage shows the two masked figures calmly returning to their getaway vehicle after murdering staff at the satirical magazine.
The pair reload their weapons, before one shouts: "We have avenged the Prophet Mohammed, we have killed Charlie Hebdo."
It then shows the gunmen firing on a police car as they made their escape.
The vehicle, lights flashing, is forced to reverse at speed as the killers get out of their own car, aim their weapons and open fire.
The fundamentalist brothers Said and Cherif Kouachi killed 12 people in last Wednesday's deadly attack on Charlie Hebdo, including two policemen.
One of the officers was shot at point-blank range as he lay wounded on the ground.
Their accomplice, Amedy Coulibaly, gunned down a police officer before killing four people in a Jewish supermarket in the French capital.
All three died in shoot-outs with police on Friday.
