The CIA and Pakistani army are electronically tracking the large caravan of people on foot and horseback through the rugged mountain area of Pakistan between the borders with Iran and Afghanistan, Pakistani officials told ABCNEWS.

Bin Laden may be traveling with the caravan and may be on foot.

Officials have cast a net around the caravan, using electronic U.S. surveillance and planes with cameras that can see through darkness to monitor its movement along a trail.

U.S. officials say they are not 100 percent sure that bin Laden is in the caravan, but they have a high degree of probability that he is and have closed off the area to all other traffic.
