He says the victims' hands were bound and they had been shot in the head, execution-style.

Al-Zahawi says authorities believe the people were killed about two years ago by Al Qaeda in Iraq.

On Wednesday, a mass grave was found in a Shiite neighborhood in Baghdad. Iraqi authorities say the remains of at least 15 people were removed.
