Ghor governor Nasir Khazeh has accused IS of revenge attack after one of their local commanders was killed on Tuesday
At least 30 civilians, including children, were killed by suspected Islamic State militants in Afghanistan's Ghor province, authorities said on Wednesday.
The local government announced the killings on Wednesday and alleged that it was a retaliation for the death of an IS local commander the previous day.
"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 (Wednesday) morning," he added.
Although the local government has blamed Islamic State members for the attack, the militant group has not claimed responsibility for the attack so far.
The civilians were abducted from north of Firoz Koh, the capital of Ghor, late on Tuesday.
The militant group is slowly extending its reach in Afghanistan and becoming a direct competition to the Afghan Taliban.
Islamic State has continued to wage deadly assaults in the country despite President Ashraf Ghani declaring in March that they had driven out the group from the country after months-long operation.
