Roadside bomb kills 11 Afghan civilians
The blast occurred when the passengers were travelling from remote Nawa district to the provincial capital Lashkar Gah on Friday, government spokesman Omar Zhwak told AFP.
"The blast was powerful and all those on board the van were killed," Zhwak said, adding that officials were trying to determine whether any women or children were among the victims.
Helmand police chief Agha Noor Kentoz blamed the Taliban for the blast, saying the road had been mined to target Afghan security forces who frequently use it.
The Taliban were not immediately reachable for comment.
