BAGHDAD, July 3 (Xinhua) -- Up to 25 people were killed and 75 wounded in a truck bomb explosion in the city of Diwaniyah, the capital of Muthanna province in southern Iraq on Tuesday, a local police source said.
"Our latest reports said that 25 people were killed and 75 others wounded by the truck bomb attack in Diwaniyah," the source told Xinhua on condition of anonymity.
The blast occurred before midday when a booby-trapped truck ripped through a busy marketplace in al-Urouba neighborhood in central Diwaniyah, some 180 km south of Baghdad, the source said.
Earlier, the source put the toll at 20 killed and 40 wounded by a car bombing.
Iraqi security forces sealed off the scene, while ambulances and civilian cars evacuated the victims to the city's hospitals, the source added.
Diwaniyah authorities imposed a traffic ban in the central part of the city until further notice after the attack, he said.
Sporadic high-profile bomb attacks are still common in the Iraqi cities despite the dramatic decrease of violence since its peak in 2006 and 2007 when the country was engulfed in sectarian killings.
