U.S. military officials tell ABC News cross-border attacks by the Taliban are up "300 percent" since President Musharraf declared a "truce" with tribal leaders in the troubled Northern Waziristan region that borders Afghanistan.
"Politically, it is very sensitive for us to raise this issue with Pakistan," said a senior NATO officer in Kabul. "But the facts are the facts."

Although the peace deal with Islamabad specifically forbade the Pakistani tribesmen from forming a parallel government, Taliban rulers in the region have issued a strict legal code, even announcing plans to begin taxing vehicles that pass through their district.
