Washington (Agencies): The Pentagon in its report said that the top Al-Qaeda leadership based in Pakistan continues to plan attacks against the US and its allies.

"Afghanistan is where al Qaeda, given sanctuary by the Taliban, planned the attacks that murdered more than 3,000 innocent people on 11 September 2001. Al Qaeda senior leadership remains in Pakistan and intends to continue to attack the United States, allies, and our partners," the Pentagon said in its report titled 'The National Military Strategy (NMS) of the United States of America 2011'.

The Nation's strategic objective is to disrupt, dismantle, and defeat al Qaeda and its affiliates in Afghanistan and Pakistan and prevent their return to either country, the report said.

The Pentagon said the threat of violent extremism is not limited to South Central Asia.

"Terrorists' abilities to remotely plan and coordinate attacks is growing, sometimes facilitated by global illicit trafficking routes, extending their operational reach while rendering targeting of their sanctuaries more difficult," it said.
