Earlier Anonymous released a video on YouTube saying that
Friday 13 November our country France was attacked in Paris for two hours by multiple terrorist attacks claimed by you, Islamic State. These attacks cannot go unpunished. That was 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. Know that we will find you and we will never let up. We are going to launch the biggest ever operation against you. Except very many cyber attacks. War is declared. Prepare yourselves.
Know this. French people are stronger than you and will come out of this atrocity even stronger. Anonymous sends its condolences to the families of the victims.
We are Anonymous. We are legion. We don’t forgive. We don’t forget. Expect us.
