Iraqi police say three car bomb explosions in the mainly Shi'ite southern city of Amarah have killed at least 40 people and wounded about 125 more.
Police say the blasts detonated in quick succession on Wednesday, targeting a garage, a market and a local police station. Many of those killed were bystanders who had gathered at the site of the first blast.
Iraq's southern Shi'ite-majority areas have been largely free from large-scale attacks. But fighting among rival Shi'ite factions in the region has intensified as the British military hands over security responsibilities to Iraqi authorities.
Separately, the U.S. military says coalition forces killed 14 terrorists and detained 12 suspects during operations since Tuesday, targeting al-Qaida-linked militants in central Iraq.
