BAGHDAD (AP) – A pair of suicide car bombings Sunday devastated the heart of Iraq’s capital, killing at least 147 people in the country’s deadliest attack in more than two years. The bombs targeted two government buildings and called into question Iraq’s ability to protect its people as U.S. forces withdraw.

The bombings show that insurgents still have the ability to launch horrific attacks even as violence has dropped dramatically in Iraq. Many fear such attacks will only increase as Iraq prepares for crucial January elections.

The dead included 35 employees at the Ministry of Justice and at least 25 staff members of the Baghdad Provincial Council, said police and medical officials speaking on condition of anonymity because they were not authorized to speak to the media. At least 721 people were wounded, including three American contractors.
