Paris: The Anonymous hacking network has declared war on the Islamic State in a YouTube video.
The "hacktivist" collective vowed vengeance for attacks in Paris, claimed by IS, that left 129 dead and hundreds injured, some of them critically.
Following the Paris attacks, the group has said it will launch "cyber attacks" against the terrorist group.
The Anonymous clip opens with thundering orchestral music, displaying the Anonymous logo of a suited figure with a question mark for a head.
The IS, a militant group that has overrun vast swaths of territory in Iraq and Syria, claimed responsibility for the bloody Paris carnage that killed at least 129 people and injured hundreds of others.
The alleged mastermind of one of the worst terrorist attacks in Paris, Abdelhamid Abaaoud, was killed on Friday. Abaaoud was eliminated in Saint-Denis after a violent exchange of gunfire between security personnel and terrorists.
