Washington, Jan. 8: Pakistan's troubled tribal areas are a threat not only to the US led operation in Afghanistan, but also to India and the whole region, the US has said.

"Pakistan's increasingly turbulent border region poses threats not just to the US mission in Afghanistan, but also to India, as shown by the Mumbai attacks, " the Daily Times quoted US National Security Adviser Stephen Hadley, as saying.

Washington, alarmed by the volatile situation in the Pakistan-Afghan border region, has shown serious concern over the increasing activities of the Taliban and other extremist groups.

Hadley said that the real issue was the deteriorating condition of Pakistan, and if the extremists succeed in taking command over Pakistan then the consequences would be far reaching.

He said that the US led `war on terror' in Afghanistan can not yield result unless Pakistani extremism is rooted out.

"You can't really solve Afghanistan without solving Pakistan," Hadley said. (ANI)
