A roadside bomb attack has blown up a car in a remote southwestern province of Afghanistan, killing 10 civilians, the interior ministry said on Monday.
Another civilian died in a separate bomb blast in the same region, it added.
The first bomb went off as civilians drove over the device in the Muqur district of Badghis province on Sunday, the ministry said in a statement.
"The mine was planted by the enemies of Afghanistan on a public road," the statement said without identifying a specific group.
The Taliban is the biggest militant group waging an eight-year insurgency to evict Western troops and topple the US-backed Afghan government and has been blamed for similar attacks in the past.
Taliban militants make wide use of crude bombs planted on roadsides and used to attack military forces and other targets.
The devices are the biggest cause of military casualties, according to Afghan and foreign military commanders. There are about 120,000 US-led and NATO forces deployed in Afghanistan to fight the Taliban.
