Officials say four car bombs in Shiite-majority parts of central and southern Iraq have killed at least eight people and wounded 31.

Police say the deadliest blasts on Sunday took place in and near the central city of Kut, where two parked car bombs targeted an industrial area and a gathering of construction workers.

Two police officers said at least five people were killed and 26 others wounded.

Another police officer said back-to-back car bombings in the southern city of Basra killed three people and wounded five.

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