An al-Qaida spokesman lashed out at moderate Muslims in a video sermon posted online Thursday, accusing them of promoting Western ideas that lure other Muslims away from holy war. In a 45-minute video posted on a militant Web site, Abu Yahya Al-Libi said clerics who support unity among followers of different religions aim only to "court favor and flatter" the West. "The duty of the Islamic nation is not to emulate the infidel nations, nor to lick their boots nor satisfy them...nor even look for ways to coexist," Al-Libi said. The footage shows the bearded al-Qaida figure speaking directly into the camera, in front of a mud wall that could be the side of a house or mosque. He wears a black turban and traditional white Muslim gown. Al-Libi said Western powers have succeeded in winning over some Muslims to help "propagate their theories," and admonished some moderate clerics for using words like `non-Muslim' to describe what he called "infidels."
