Baghdad Bomb Attacks Kill 40

The Associated Press reports:

Four bombs ripped through Shiite neighborhoods in Baghdad Thursday evening, killing at least 40 people in the worst violence the capital has seen in months, Iraqi officials said. An American civilian aid specialist working to improve education in Iraq was killed in a separate attack.

The violence underscored the fragile nature of the security gains in Iraq at a time when American forces are preparing to withdraw by the end of this year and the challenges facing the State Department personnel and American contractors who would continue on after the U.S. military is gone.
