Washington, Jun 17: The Islamic State has emerged as the most potent terrorist threat globally but in the Af-Pak region the space is dominated by other terrorist groups like Taliban, Haqqani network and Lashkar-e-Taiba, America’s top spymaster has said. “There are the organisations in the Af-Pak area led by the Taliban, the Haqqanis and Laskar-e-Taiba that continue to engage in terrorist attacks,” CIA Director John Brennan told Senators in response to a question on the dangers being posed by non-ISIS affiliate terrorist organisations.(Also Read: US rules out mediation between Afghanistan, Pakistan)Also Read - Blast Hits Mosque in Afghanistan's Nangarhar Province, 12 Injured: Report

Testifying before the Senate Select Committee on Intelligence yesterday he said US is working closely with India to prevent these terror outfits from carrying out attacks. “We work very closely with services (security forces) in the area, including the Indians and others to try to guard against their ability to carry out attacks,” he said. “So this is something that we continue to have to dedicate a lot of resources to. As you know, Ayman al-Zawahiri, the head of al-Qaeda, still is out there and continues to put out audio statements and other things exhorting his followers,” Brennan said.

It drove them out,” he said. “There is an active effort underway to continue to dismantle and destroy that organisation,” the CIA official said.
