Al Qaeda's second-in-command on Friday accused the United States of leading a crusade to turn Pakistan into a divided nation and urged Pakistanis to join in a jihad to resist. "The war in the tribal areas and Swat is an integral part of the crusade on Muslims across the world," Zawahri said in the tape posted on an al Qaeda-linked website.In the 22-minute video address entitled "Path of Doom" he reiterates comments made in July calling for Pakistanis to wage war against the American "crusaders" and the Pakistani army. "There is no honour for us except through Jihad," Zawahri said. "People of Pakistan ... back the jihad and mujahideen with your persons, wealth, opinion, expertise, information and prayers and by exhorting others to help them and preach their message."
