At least 22 people died on Sunday when a suicide bomber activated his explosives-rigged car among day laborers waiting to be hired in the central Iraq city of Hilla, Reuters reported.
Police in the mainly Shi'ite city 100 south of Baghdad said 49 people were injured in the early morning attack, when hot shrapnel tore through the crowd of workers as they gathered around the bomber's minibus.
Other attacks in other areas of Iraq killed 30 people and wounded 58, raising the country's death toll to 52 by midday Sunday.
Sunday's attacks followed the assassination of a prominent Shi'ite politician on Saturday. Ali al-Adhadh of the Supreme Council for the Islamic Revolution in Iraq (SCIRI) was shot dead with his wife as he drove in mainly Sunni west Baghdad.
