A car bomb explosion in the holy city of Karbala has killed 68 people. After the attack, an angry crowd gathered and began attacking Iraqi police, accusing them of failing to protect the population. Elsewhere in Iraq, nine U.S. soldiers have been killed in the last two days.
Iraqi television images from Karbala showed a man running down a smoke-filled street holding a lifeless baby above his head.
Ambulances had rushed to the scene, in a crowded area full of shops and restaurants in the city, 100km (70 miles) south-west of Baghdad.
Angry people gathered at the blast site, many of them searching frantically for missing relatives, the Associated Press news agency reported.
