A WAVE of car bombings has killed 34 people in mainly Shiite areas of Baghdad.
It is the latest in a surge in violence that has been the most serious challenge to the government's efforts to achieve stability across Iraq.
The attacks came as Iraqi Shiites were celebrating the birthday of Imam Ali, the cousin and son-in-law of the Prophet Mohammed and Shiite Islam's most sacred martyr.
