Pakistan warned the U.S. not to stray across the Afghan border into its territory after a gunbattle between the anti-terror allies that was praised by tribesman on Friday as a victory against Washington. As if to underline the point that Pakistan can beat al-Qaida and Taliban militants without American firepower, a top general said an offensive in another frontier province had killed more than 1,000 suspected insurgents and predicted the region would be "stabilized" within two months. Still, he also showed reporters photos of militant tunnel systems and trenches in Bajur, suggesting more tough fighting ahead in an area that is considered a likely hiding place for Osama bin Laden and other top al-Qaida leaders.
