Worth a look:

The Pakistani regime of Gen. Pervez Musharraf has been negotiating truces - with the Bush administration's encouragement - with Islamic separatists in North Waziristan and South Waziristan, mountainous tribal areas along the Afghan border where U.S. officials think bin Laden may be hiding.

In return, Pakistani officials are promising to restrict the country's troops in the area to major bases and towns and to pour huge amounts of aid - much of it from the United States and other nations - into the destitute region, according to American officials.

But as the truces take hold, separatists have been crossing into Afghanistan to fight alongside Taliban and al-Qaida fighters, according to Western and Afghan officials.
