Calling it #OpCharlieHebdo, after the name of the satirical French magazine that was the focus of the attacks, they also published a statement summarizing the points made in the video as well:
Never attack the media
Message to the enemy of the freedom of speech.
January 7, 2015, freedom of speech has suffered an inhuman assault. Terrorists broke into the premises of the “Charlie Hebdo” newspaper and shot in cold blood several satirical cartoon artists, journalists and two policemen. The killers are still at large. Disgusted and also shocked, we can not fall to our knees. It is our responsibility to react.
First, we wish to express our condolences to the families of the victims of this cowardly and despicable act. We are all affected by the death of Cabu, Charb, Tignous and Wolinski, great artists that marked their talent throughout the history of the press and died for freedom. We do not forget the other victims killed and injured in the attack that were the targets of these murderers.
It is clear that some people do not want, in a free world, this inviolable and sacred right to express in any way one’s opinions. Anonymous will never leave this right violated by obscurantism and mysticism. We will fight always and everywhere the enemies of freedom of speech. Charlie Hebdo, historical figure of satirical journalism has now been targeted. Anonymous must remind every citizen that the freedom of the press is a fundamental principle of democratic countries. Freedom of opinion, speech and to publish articles without any threat, and stress is a right “inalienable.” Anonymous has always fought the slayers of these rights and will never allow a person to be shot down radically for publishing an article, a drawing, an opinion …
Freedom of speech and opinion is a non-negotiable thing, to tackle it is to attack democracy. Expect a massive frontal reaction from us because the struggle for the defense of those freedoms is the foundation of our movement.
We are Legion.
We do not forgive.
We do not forget.
