Khyber Pass Is Porous Front in Terror War

The remote and mountainous Khyber Pass (search) border region between Afghanistan and Pakistan (search) is a strategic front in the War on Terror, and FOX News was recently allowed access to the rugged area.

FOX accompanied a congressional delegation that visited the region to monitor the Pakistani government's efforts to patrol the pass, which is used by U.S. troops to get supplies into neighboring Afghanistan (search).

"You get an idea how rugged this place is, how difficult it is to find someone you are looking for," said Rep. Jeff Flake, R-Ariz., alluding to the hunt for Al Qaeda leader Usama bin Laden (search).

Pakistan has increased the number of guards at the Khyber Pass in an attempt to find the terror mastermind, but the region is controlled by tribal leaders who believe they have a duty to protect any guest who seeks shelter there.

The U.S. wants to make sure the Pakistanis don't allow that to happen.

"The War on Terror is Pakistan's war, too, and in the interest of the U.S.A. to make sure they win it," said Rep. Mike Pence, R-Ind., the leader of the delegation.

Editor's Note: FOX News' Molly Henneberg was embedded with a delegation of lawmakers from the House International Relations Committee who traveled to Afghanistan, Pakistan and Germany. This is the second in a series of reports. Part one focused on a madrassa in Pakistan and part three will focus on tensions between the U.S. government and Afghanistan on the eradication of poppies, which are used to make heroin.
