Hackers claiming to be with the group Anonymous say they have hacked a jihadist website in retaliation for the terror attack on French satirical magazine Charlie Hebdo.
The website ansar-alhaqq.net, a French jihadist site, currently redirects to Duck Duck Go, a search engine. Hackers using the Twitter handle @OpCharlieHebdo claimed responsibility.
Anonymous also named dozens of Twitter accounts that the hacktivist group says belong to jihadists.
The hackers posted the Twitter handles on Pastebin, a website that lets people post information anonymously online.
