Hacktivist group Anonymous, which has claimed responsiblitiy for a slew of cyber attacks on Turkish webistes, said it would continue its online warfare until Turkey withdrew its support to Sunni militant outfit Islamic State (Isis).

The one-week-long DDoS (Distributed Denial of Service) attack on Turkey's Internet services from 14 December had brought down about four lakh ".tr" domains by overloading up to 40 Gbps of traffic.

This was initially attributed to Russian hackers as Turkey had shot down a Russian fighter jet near the Syrian border last month. However, Anonymous' claim has cleared the air over the issue.

The group had recently launched an operation — #OpIsis — declaring war on Daesh over the Paris attacks that killed 130 people.

"Greetings, citizens of the world, We are Anonymous," the cloaked figure in a Guy Fawkes mask introduces itself on the video.

"As many of you have heard, Turkey is supporting Daesh by buying oil from them, and hospitalising their fighters. We won't accept that (President Recep Tayyip) Erdogan, the leader of Turkey, will help Isis any longer.

"The news media has already stated that Turkey's Internet has been the victim of massive DDoS attacks. This made Turkey shut down its Internet borders and deny anyone outside the country access to Turkish websites.

"Dear government of Turkey, if you don't stop supporting Isis, we will continue attacking your Internet, your root DNS, your banks and take your government sites down.

"After the root DNS, we will start to hit your airports, military assets and private state connections. We will destroy your critical banking infrastructure.

"Stop this insanity now, Turkey. Your fate is in your own hands. We are Anonymous, we are vision, we do not forgive, we do not forget. Expect us!"
