Al Qaeda Group Claims Sunday Attack in Baghdad

An al Qaeda front group is claiming responsibility for a weekend attack in the heart of Baghdad that killed 12 people.

In a statement posted on a militant website Tuesday, the Islamic State of Iraq took credit for the assault which targeted an Iraqi military facility in Baghdad.

The hour-long assault Sunday on the headquarters of the Iraqi Army's 11th Division was the second assault on the complex in less than a month and demonstrated the challenges Iraqi security forces are still facing.

U.S. troops living and working at the complex helped Iraqi troops repel the assault, marking the first exchange of gunfire involving American forces in Iraq since President Barack Obama declared an end to combat operations on Aug. 31.
