McCain stumbles on Iran-Iraq link

Senator McCain, at a news conference in the Jordanian capital of Amman, accused Iran of supporting the Sunni extremist group al-Qaeda in Iraq.

US officials believe Iran has been backing Shiite extremists in Iraq, not a Sunni group like al- Qaeda.

"It's common knowledge and has been reported in the media that al Qaeda is going back into Iran and is receiving training and are coming back into Iraq from Iran. That's well known and it's unfortunate," Senator McCain said.
