|'Massacre': The gunmen are seen brandishing Kalashnikovs as they move in on the injured police officer from their vehicle outside the office|
Two masked attackers brandishing Kalashnikovs burst into the Charlie Hebdo headquarters, opening fire on staff after seeking out journalists by name.
Those executed also included four of the most famous cartoonists in France – men who had regularly satirised Islam and the Prophet Mohammed – along with the magazine’s editor-in-chief, Stephane Charbonnier.
The killers were heard to shout 'the Prophet has been avenged' and 'Allahu akbar!' as stalked the building.
Horrific footage also emerged showing an injured police officer slumped on the pavement outside the office as the two gunmen approach.
In an apparent desperate plea for his life, the officer is seen slowly raising his hand towards one of the attackers, who responds by callously shooting him in the head at point-blank range.
Despite a shoot-out with armed officers, the ‘calm and highly disciplined’ men who reportedly spoke perfect French were able to escape in a hijacked car and remain on the loose.

Charlie Hebdo’s tweet appeared to tease the leader of the Islamic State militant group, ISIS.
In the past, the newspaper stirred outrage among some Muslims after it published a satire of Prophet Muhammad and Islam.
In 2011 its offices were firebombed after it published a cartoon of the prophet on its cover promising “100 lashes if you don’t die laughing!”
