"A mine planted by militants struck a civilian car on a road in Muqar district wounding six civilians including women and children," Alkozai told media.
The official also blamed the Taliban militants for organizing the roadside bomb, saying the armed insurgents often plant mines on the roads to target both military vehicles and civilians.
Taliban militants who are active in parts of Badghis province with Qala-e-Naw as its capital 555 km northwest of Kabul have yet to claim responsibility.
Civilians often bear the brunt of war in Afghanistan as 2,563 were killed and 5,676 injured in the first nine months of 2019, according to a report of United Nations Assistance Mission in Afghanistan.
