CAIRO, Egypt - Al-Qaida's No. 2 Ayman al-Zawahri warned of "traitors" among insurgents in Iraq and called on Iraqi Sunni Arab tribes to purge those who help the Americans in a new videotape posted Monday on the Web.
Al-Zawahri's comments were aimed at undermining so-called "awakening councils" — the groups of Iraqi Sunni tribesmen that the U.S. military has backed to help fight al-Qaida in Iraq and its allies.
Some Sunni insurgent groups have fought alongside American forces, and the U.S. military has touted the councils as a major factor in reducing violence in war-torn regions like Iraq's Anbar province
