Last week the war against ISIS was brought back into focus when several terrorists bombed, took hostages and killed numerous civilians in several locations of the French capital, Paris. In a new video announcing the new campaign, an unidentified man donning the iconic mask said "These attacks cannot go unpunished. That's why Anonymous activists from all over the world will hunt you down. Yes, you, the vermin who kill innocent victims - we will hunt you down like we did to those who carried out the attacks on Charlie Hebdo. So get ready for a massive reaction from Anonymous."
