Car bombs have killed 30 people and wounded more than 70 others in Iraq in one of the worst outbreaks of violence in recent weeks.21 people were killed and 52 wounded in an explosion near the main central bus station in the Shi’ite holy city of Kerbala, south of Baghdad. Two cars also exploded in the capital early on Sunday: a suicide car bomber hit an Iraqi army patrol in the northern district of Aadhamiya, killing eight and wounding fifteen, and a second car bomb exploded at a major traffic intersection, killing one civilian and wounding five. The Iraqi Interior Ministry says that 42 bodies have been found in Baghdad in the last day or so linked to sectarian conflict. The southern city of Basra is largely calm after a curfew and the heavy presence of Iraqi police and troops. Five Iraqis were killed and 42 wounded in violence following the crash of a British military helicopter on Saturday. Initial reports say that up to five Britons died in the crash.
