The coordinated attacks Thursday by a suicide car bomber and another man wearing a vest with explosives occurred one day after a horrific blast at a poor east Baghdad neighborhood that killed 18 children and teenagers who had swarmed around a U.S. Humvee to get candy and toys.
   Up to 27 people died in the Wednesday blast-including one American soldier. The bomber drove straight into the crowd of children.
   The suicide bombing Wednesday stunned the largely Shiite neighborhood. Terrified parents rushed outdoors after the bombing to find the bloodied, mangled bodies of their children scattered along the street.
   Twelve of the dead were 13 years or younger and six were between 14 and 17, police Lt. Mohammed Jassim Jabr said.
   A1 Qaeda in Iraq denied any involvement in the bombing, issuing a statement that said the group is "not in the least responsible" for the attack.
   The statement’s authenticity could not be verified. But it suggests the militant group is aware of the backlash the death of so many children could generate, even among Iraqis who oppose the presence of U.S.-led forces.
   One woman said of the attack, "This tarnishes the image of the true resistance."
