Clinton attacks Pakistan over border terror failure

US Secretary of State Hillary Clinton launched a scathing attack on Pakistan for failing to hunt down al Qaida inside its borders, saying the government knew where the terror leaders were hiding.

American officials have long said that al Qaida mastermind Osama bin Laden and senior lieutenants of the network accused over the September 11, 2001 attacks operate out of the rugged terrain along the border with Afghanistan.
