In this Thursday, Nov. 27, 2008 file picture, Pakistani army 130mm artillery guns fire towards militant positions in the Bajur tribal region on the border with Afghanistan, Pakistan. Pakistan is battling surging attacks by al-Qaida and Taliban militants. Most of them are based in the rugged and lawless tribal region across from Afghanistan, where U.S. and NATO forces are fighting an increasingly tenacious Islamist insurgency. Al-Qaida leaders Osama bin Laden and Ayman al-Zawahri are believed to be hiding somewhere along the border. (AP Photo/Emilio Morenatti, File)
