"A civilian vehicle was traveling along a road to a local marketplace in Nahri Sarraj district at around 7:30 a.m. local time. The ill-fated vehicle ran over a roadside bombing, leaving the casualties," spokesman Omar Zhwak told Xinhua.
Two women were among the wounded, Zhwak said, blaming Taliban militants for placing the bomb in the province 555 km south of Afghan capital Kabul.
Taliban militants, who have been waging an insurgency for more than one decade, use Improvised Explosive Devices (IEDs) to launch roadside bomb attack on security forces but the lethal weapon also inflicted casualties on civilians.
A total of 2,754 civilians were killed and 4,805 injured in conflict-related violence in 2012, according to a UN report released on February 19 in Kabul.
The UN report attributed 81 percent of the civilian deaths to the attacks of Taliban insurgents and other armed groups, another 8 percent of the deaths were attributed to Afghan and NATO-led forces and 11 percent were unattributed.
The IEDs were the single largest killer of Afghan civilians in 2012, leaving 868 people dead and 1,663 others injured, the report added.
