Pentagon officials said they think bin Laden is hiding along the mountainous Pakistan-Afghan border, but they said they do not know bin Laden's exact location.

The officials said they think the fugitive terrorist leader is increasingly facing pressure from Pakistan's close efforts with the United States as well as the cooperation of some tribes that rule the largely ungoverned region along the border.

The Arab television network Al-Jazeera aired video Monday showing some 2,000 men from a tribe in the Wana border region of Pakistan who, under pressure from the Pakistan government, have joined the hunt for al Qaeda members.

The US military recently said it was increasing efforts to findbin Laden, who has eluded the United States for years. Pentagon officials insist that it's only a matter of time before bin Laden is found.
