Hacktivist group Anonymous has come out to avenge the attacks on the office of Paris-based magazine Charlie Hebdo in which 12 people were murdered.
The Belgian 'branch' of Anonymous posted a video message to YouTube describing a new campaign against jihadists, called #OpCharlieHebdo.
The video, which features someone wearing the Guy Fawkes mask and speaking with their voice obscured, explains (in French) that its members have decided to "declare war on you, the terrorists" - referring to Al-Qaeda and ISIS specifically.
"We will track you down - every last one - and will kill you,” the spokesman says. "You allowed yourselves to kill innocent people, we will therefore avenge their deaths."
The figure says that 'hacktivists' from around the world will track all of jihadist activities online and close down their accounts on Twitter, YouTube and Facebook.
"You will not impose your sharia law in our democracies, we will not let your stupidity kill our liberties and our freedom of expression. We have warned you; expect your destruction."
