Graphic footage of two of the suspects believed to be among those who carried out a fatal attack at a magazine in Paris has emerged.
At least 12 people are believed to have been killed in the attack and the Paris mayor’s office says the suspects are still at large.
The mobile phone footage shows two masked, black-clad gunman leaping out of a black Citroen car whose back window has been blasted out.
The men rush up to a obviously wounded police officer lying face down on the pavement.
He raises his hand in apparent surrender but one of the gunman aims his weapon and fires, rendering the victim motionless. The gunmen run back to the car and drive off.
Le Figaro reported that the gunmen used automatic weapons, believed to be AK-47s, quoting a police source. There were also multiple, but unconfirmed reports of a rocket launcher seen on the scene.
The offices of Charlie Hebdo were fire-bombed in 2011 after it published a call-out for the Prophet Mohammed to guest-edit the magazine.
The publication, which lampoons all of the world's religions, was under fire in 2007 for re-printing the Danish cartoons of the prophet Mohammad that sparked worldwide protests.
The last tweet from the magazine's Twitter account was a cartoon of Islamic State leader Abu Bakr al-Baghdadi, wishing him "best wishes, by the way."
