Iraqi officials say suicide attacks in two Baghdad suburbs have killed at least 14 people and wounded dozens.

A police officer said Sunday that a suicide car bomb struck a checkpoint in the eastern suburb of Hussainiyah late the night before, killing six civilians and four soldiers. He says 28 other people were wounded in the attack.

Another police officer says a suicide car bomb struck a passing military convoy at around the same time in the southern suburb of Arab Jabour, killing four soldiers and wounding eight others.

Two medical officials confirmed the casualty figures. All officials spoke on condition of anonymity as they were not authorized to release information.

No group has claimed responsibility for the attacks, which bore the hallmarks of Islamic State extremist group.
