Iraq car bombings: Attacks hit mainly Shia cities

A wave of car bombings across central and southern Iraq has killed at least 30 people, police and medics say.

Most of the attacks took place in cities with a high concentration of Shia Muslims - including Kut, Najaf, Mahmoudiya, Nasiriya and Basra.

Iraq has been hit by almost daily attacks, raising fears of a return to the worst levels of sectarian violence.
