Hacker group Anonymous has declared "war' on Isis, in response to the attacks in Paris that left over a hundred people dead.


Members of the online collective have posted a video which says the group will continue the work against Isis, which began after the Charlie Hebdo attacks in January.


In a video posted soon after the attacks, a person claiming to represent the group warns members of Islamic State that it intends to hunt them down. It said that it would "unite humanity' in the operation, which it claimed would use hacking to weaken the group.
