Iraqi officials say a suicide attacker struck Monday near the Interior Ministry in central Baghdad, killing at least six people. Officials say dozens of other people were wounded.

Witnesses say the suicide bomber detonated a car bomb adjacent to a checkpoint during the morning rush hour.

Monday's attack follows a wave of violence Thursday that left about 70 people dead and nearly 200 wounded. Thursday's coordinated attacks from car bombs, roadside bombs and sticky bombs were the country's worst violence in months.

The bombings occurred just days after U.S. troops finished their withdrawal from Iraq.
