BAGHDAD (AFP) - A series of bombings and gun attacks killed seven people in Iraq on Thursday, including four who died in a car bombing in a predominantly Shia city south of Baghdad, officials said. The continuing violence, primarily carried out by militants bent on destabilising the Shia-led government, also underlines concerns over the capabilities of Iraq’s security forces nearly a year after US forces departed. In the deadliest attack, a car bomb in the centre of Hilla, around 95 kilometres (60 miles) from Baghdad, killed four people and wounded 20, a medic and a police officer said. Both spoke on condition of anonymity.
