Rise of ISIS in Afghanistan
The incident occurred late Tuesday north of the provincial capital Firoz Koh, with the government calling it a revenge attack after a local Daesh commander was killed.
"Our security forces with the help of locals conducted an operation and killed a Daesh (IS) commander yesterday. Daesh fighters in return abducted around 30 villagers, mostly shepherds," Ghor Governor Nasir Khazeh told AFP.
"Their dead bodies were found by local people this morning."

There has so far been no official claim of responsibility from the group.
The killings underscore unravelling security in Afghanistan as the resurgent Taliban continue a push into urban centres 15 years after they were toppled from power by the US invasion.
Daesh fighters are also making steady inroads into Afghanistan, winning over sympathisers, recruiting followers and challenging the Taliban on their own turf, primarily in the country´s east.
