BAGHDAD — A series of bombings Sunday across the Iraqi capital, Baghdad, killed at least 14 people and wounded 41, police officials said.

The deadliest attack took place at the Aden checkpoint in Baghdad's Khazimiyah district, where a suicide car bombing killed eight people, including five civilians, and wounded 23.

In Baghdad's al-Askan district, a car bomb killed at least four people and wounded 11 on a commercial street as people gathered after sunset to break their daily fast for the Islamic holy month of Ramadan.

Police also said a roadside bomb on a commercial street in Baghdad's al-Amal neighborhood killed two people and wounded seven.

Medical official corroborated the casualty figures. All spoke on condition of anonymity as they are not authorized to brief journalists.

No one immediately claimed responsibility for the attacks. However, the Islamic State militant group is often behind assaults on checkpoints as it seeks to challenge Iraqi security forces amid intensifying battles in northern and western Iraq.
