Anonymous campaign #OpCharlieHebdo claims first victim as French jihadist website knocked offline

Update: Anonymous publishes 14 alleged jihadist Facebook profiles

Up to 10 websites have been knocked offline by hacktivist group Anonymous in retaliation for the Charlie Hebdo massacre.

Anonymous, the amorphous online activist group, last week announced the launch of #OpCharlieHebdo - a campaign to avenge the 17 people killed in France last week by targeting jihadist websites.

On Saturday evening the first victim of the campaign was announced with the jihadist forum Ansar al Haqq knocked offline and visitors now redirected to search engine Duck Duck Go.

The Ansar al Haqq website is still offline as of Monday morning (12 January).

Anonymous also listed 14 other websites on Pastebin which it is targeting as part of this campaign. At the time of publication nine of the 14 websites were inaccessible.

In a video posted on YouTube, Anonymous said: "Attacking freedom of speech is attacking Anonymous. We will not permit it. Any organisations or enterprises linked to those terrorists attacks should expect a massive reaction from Anonymous. We are tracking you down. We will find you and not leave you any rest."

The group leading the campaign last week published a list of Twitter accounts that it claims belong to known jihadists. A series of tweets in English and in French implore other Twitter users to "get the word out" and ask Twitter to block them.

Last week, in the wake of the attacks in Paris, a number of websites associated with Islam and Islamic practice were also attacked, but Anonymous has not claimed any responsibility for these attacks.

Some on social media have decried the Anonymous campaign, calling the group hypocritical for silencing one voice in the name of freedom of expression.
