ISIS a formidable adversary, to intensify global attacks: CIA

Washington: Describing the Islamic State as a formidable adversary, CIA chief on Thursday made a candid admission that the US efforts to contain the dreaded terror group have not reduced its terrorism capability and global reach.

Testifying before a Senate Committee, the CIA Director John Brennan told lawmakers that despite all of the progress against IS on the battlefield and in the financial realm, the American efforts have not reduced the group's ability to launch terror attacks outside of its base in Iraq and Syria.

The resources needed for terrorism are very modest and the group would have to suffer even heavier losses on territory, man-power and money for its terrorist capacity to decline significantly, Brennan said.

With the increase in pressure, Brennan felt that IS will intensify its global terror campaign to maintain its dominance of the global terrorism agenda.

Since 2014, IS has been working to build an apparatus to direct and inspire attacks against its foreign enemies, resulting in hundreds of casualties.

The most prominent examples are the attacks in Paris and Brussels, which were directed by IS leadership, he added.

"We judge that IS is training and attempting to deploy operatives for further attacks. IS has large cadre of western fighters who could potentially serve as operatives for attacks in the west.

"And the group is probably exploring a variety of means for infiltrating operatives into the west, including in refugee flows, smuggling routes and legitimate methods of travel," Brennan warned.

"Furthermore, as we have seen in Orlando, San Bernardino and elsewhere, IS is attempting to inspire attacks by sympathisers who have no direct links to the group. Last month, for example, a senior IS figure publicly urged the group's followers to conduct attacks in their home countries if they were unable to travel to Syria and Iraq," he said.

Brennan told Senators that IS is gradually cultivating its global network of branches into a more interconnected global organisation.

The branch in Libya is probably the most developed and the most dangerous.

"We assess that it is trying to increase its influence in Africa and to plot attacks in the region and in Europe," he said.
