With the Taliban on the run and a U.S.-led coalition determined to hunt him down, Osama bin Laden is running out of places to hide.
Bin Laden and his al-Qaeda network have few friends among ordinary Afghans, which means he will have to take to the hills and seek refuge with longtime comrades to elude capture.
At least one bin Laden ally, Mullah Yunus Khalis, appears to have taken control of Jalalabad in Nangarhar province, where bin Laden is believed to have several camps hidden in the mountains.
Until the Taliban fled Kabul Tuesday, bin Laden was believed to have been hiding in the mountains that surround the capital. If true, he probably would have abandoned those camps and joined the Taliban on their march out of the area.
But where could he go?
U.S. special forces tracking bin Laden and Taliban leader Mullah Mohammed Omar are questioning Taliban defectors and prisoners, dangling millions in reward money and hoping for a communications slip-up as they monitor phone and radio transmissions.

Both men are probably still in the region, but they aren't believed to be together, a U.S. official said on condition of anonymity.
Since the U.S. air campaign began Oct. 7, U.S. jets have pummeled suspected bin Laden camps and hideouts, but the extent of damage and casualties remains unclear.
Even though the Jalalabad area is no longer under Taliban control, bin Laden could still have access to camps and caves in Nangarhar province.
Khalis, a former guerrilla leader who received considerable U.S. support during the Afghan war against Soviet invaders, is anti-Western, deeply conservative and a friend to Arab militants.
Residents who live near Khalis in Farmada, about 10 miles outside Jalalabad, said more than 1,000 Arab warriors were camped at his farm earlier this year.
Most are believed to have relocated to other camps in Nangarhar province, such as Darunta and Tora Bora. Bin Laden could be hiding in caves deep inside the mountains there. Bureau Report
