BAGHDAD — After intense U.S. assaults, al-Qaida may be considering shifting focus to its original home base in Afghanistan, where American casualties are running higher than in Iraq, the top U.S. commander in Iraq said Saturday.
"We do think that there is some assessment ongoing as to the continued viability of al-Qaida's fight in Iraq," Gen. David Petraeus told The Associated Press in an interview at his office at the U.S. Embassy.
