Afghan officials say nine people have been killed and more than 20 injured when they were struck by a roadside bomb.
The blast occurred late on July 28 in the Shahjoi district of southern Zabul Province, on the border with Pakistan.
On July29, the deputy provincial governor, Mohammad Jan Rasolyar, said a senior police official, two local policemen, and six civilians were killed in the blast.
Rasolyar said the target of the bombing was the deputy district police chief. He said 12 others, mostly women and children, were also injured.
The Taliban claimed responsibility for the attack.
According to the AP news agency, an estimated 50 to 70 Afghan policemen die every week.
There has been a recent increase in violence in Afghanistan, with the Taliban increasing its attacks on Afghan security forces and government officials.
