Anonymous has declared war on Isis, also known as Islamic State, just a day after the deadly terror attacks in Paris.

In a video released on 14 November, the hacktivist group has threatened Isis with retaliation against the dastardly terror attacks on Friday night that left at least 129 people dead.

The Isis had claimed responsibility for the massacre and threatened more such attacks on France till it continues to bomb Isis targets in Syria

Wearing the signature Guy Fawkes mask, a member of Anonymous is seen as saying: "Anonymous from all over the world will hunt you down. You should know that we will find you and we will not let you go... We will launch the biggest operation ever against you." 

"War is declared. Get prepared. The French people are stronger than you and will come out of this atrocity even stronger," the speaker says. 

Anonymous also released a list of 1,000 Twitter accounts of Isis militants and supporters. "We are the collective today we bring you a mass amount of isis twitter accounts for your enjoyment, namaste," the hacktivist group said. 

Eight armed terrorists last Friday attacked six locations in Paris, including Bataclan theatre, restaurants and cafes, killing at least 129 people and injuring 349 others.
