Live from Baghdad: New Sunni alliance forming to oppose Al Qaeda in Iraq

USA Today reports, er, yesterday, that more Sunnis are joining the fight:

More than 10 Iraqi tribes in the Baghdad area have reached agreements with U.S. and Iraqi forces for the first time to oppose al-Qaeda, raising the U.S. military's hopes that a trend started in western Iraq is spreading here.
Some of the groups, which have members who fought alongside al-Qaeda in the past, have been providing useful intelligence to U.S. forces about their former allies, according to the U.S. military.

"They know where they live and who they are," said Lt. Col. Rick Welch, a staff officer who works with tribes in the capital area.
